On a demandé à un Patent Examiner Mechanical Engineer...14 avril 2016

If given four projects of equal importance with the same due date, what would you do. Be specific

just some more info while we all wait(i know this process is painful- ive been through it a few times without good luck, unfortunately) June 13th is the tentative start date for ALL examiners for this round of hiring so that should tell you a lot. i just heard this today and apparently the Supervisors are apparently suppose to turn in their lists by tomorrow so calls/emails obviously follow after that is done. We might hear something later since the start date would be further down the road. i'll keep updating if i find out more or hear back from them. btw, the chemicals and computers i think hear back first and the electrical and mechanicals may hear back later as their interviews were conducted in that order.

I applied for EE position and just received notification that I have been selected. Last name starts with "C" and interviewed on April 13th. It seems that the selections for EE and Comp Science will begin to be sent today. It may take until Friday for HR to finish sending all decisions to the applicants. Best of luck to everyone and very grateful to all who have contributed to this posting. Moins

I interviewed on 4/13 for a BME position and received notification on 5/2 that I was selected. In a follow up email for the Declaration of Federal Employment form, they indicated a tentative start date of 6/13. Hope this info is helpful for those still waiting - good luck! Moins

If you were in a dark closet with 49 white socks and 1 black many socks would you pick so as to ensure that you exit the closet with a pair of similar colored socks

18 réponses

3 socks

All of them. In a dark closet it is hard to distinguish colors.

One pair. My socks are always bundled in matching pairs. In the dark, I can tell the diff between a bundled sock pair and a single unmatched sock. Moins

If two vehicles are identical, except for one weighing twice as much as the other vehicle, and they roll down a hill, which car reaches the bottom first? Neglect air resistance. Assume the extra mass is in the body of the vehicle.

14 réponses

The heavier car reaches the bottom first because the rotating inertia (wheels) of that car makes up a smaller percentage of of its mass. This is why the question mention /where/ the extra mass of the heavier car is. Moins

Same time... Don't listen to the rest of the shmos what we are really worried about here are the cars acceleration From FDB: F = ma = mgcos(theta) - FrictionForce = mgcos(theta) - mu*NormalForce = mgcos(theta) - mu*mgsin(theta) Divide both sides by m, and there is no mass left in equation... just a = gcos(theta) - mu*gsin(theta) Therefore, the equation is independent of mass and they arrive at the same time. Moins

They reach at the same time. Assuming the mass is included in the body and minimal friction and no air resistance, mass will not be a factor. PE will be completely transformed to KE by the bottom of hill meaning mgh=.5mv^2, mass cancels out meaning mass doesn't matter. This is similar to dropping a feather and a bowling ball on the moon. No air resistance so they hit the ground at same time. Don't over think it. That's the worst thing you can do in an interview. Moins

You are in a boat in a pool with a rock in your hand. You throw the rock into the pool. Does the water level rise, drop, or stay the same?

13 réponses

If the rock were neutrally buoyant the water level would remain the same. It is heavier than water which causes it to displace more than its own volume while in the boat compared to at the bottom of the lake. Therefore the water level of the lake would go down. Moins

These answers are troubling. The only correct answer so far is Ben. The water level goes down. Moins

The weight of the boat plus you plus the rock has already displaced the height of the water. The only time the water level will change will be when the rock is mid air. Moins

If you have a refrigerator in an isolated room (no heat in or out) and left the door to the refrigerator open, what would happen to the temperature to the room? Would it go up, down or say the same?

11 réponses

The refrigerator will warm up the room. If you look on the back of the refrigerator, you will see metal grating. Touch it. Its warm! A refrigerator is transporting heat from the inside cavity to the outside. However, the power cord running from the wall is pumping energy into the refrigerator/room. Energy is powering the refrigerator. It is also running an irreversible process, the energy dissipates out as heat and work (mostly heat), making the net temperature of the room increase. Moins

In this case, there is a net gain of energy from the refrigerator outlet into the room and no loss of energy out of the room. Thus, the room will warm up since there is a gain of energy. Moins

The temperature and overall heat content of the room will increase. Yes, the fridge it providing cooling, but it is doing this by removing heat from part of the air and dumping it into other parts of the air, all while doing work which is harnessed from the power input (electricity) from the wall. In other words, the heat in the air is just displaced from one area of air to another, so no loss nor gain of net heat, HOWEVER the work used to do this creates additional heat. If you consider this from a total energy standpoint, all energy within the room is fixed, except there's energy being added through the power input, so there's an increase in energy with time. I'm shocked at some of the other answers here, I hope those saying the temperature remains the same do not have mechanical engineering degrees. Moins

in a boat on a lake with a rock, throw the rock in the water which way does the water level move? here is a memory card- what is it made out of and how was it made?

9 réponses

no change in water level. it will be the same as it was when the rock was on the boat. Moins

the water level goes down. Think about an extreme case. You have an small item made of the worlds most dense material in the hull of the boat. Even though the volume of the item is small the weight is very heavy. This pulls the boat down and since the volume that the boat displaces will be much higher then that of the small item, when the item is thrown over board, the boat lifts further out of the water displacing less water causing the level to decrease. Moins

Archimedes Principal. Weight of rock is displacing water upwards when in the boat. When in the water it is displacing its volume. Water has to go down since the density of most rocks > water Moins
