Simon, Please see the attached file. Method First, calculate linear impulse of lid to find velocity of lid when it impacts bottom. Next, calculate conservation of momentum to determine velocity of bottom after impact Next, calculate linear impulse of bottom using velocity found in step 2 Where...

Simon, I want to keep the problem as simple as possible and would rather not consider the lid sticking or bouncing. The real world application is a heavy metal lid and base, there is not much bouncing occurring. So I did start down this track of trying to calculate the momentum needed to tip...

Hello, See attached PDF for basic depiction of an issue I am currently working on. If lid starts off with angle = 0 (closed) and I fling it open until it hits the "stop" (interferes with bottom causing it to stop), how fast must lid being traveling to tip over entire assembly? From this I want...

Hello, Trying to set up some production checks and encountered a symbol I have never seen before. I googled machine stock symbols and found something along the lines of what I need to know but could not figure out what the 3.0 besides the squiggly line means. I have attached a PDF with the...

Hello All, At work we will begin press fitting bushings into iron components. The customer has specified a range for the "push-in" and "pull-out" force so we bought a load cell to measure the values. My question is, when we approximate force on our standard 50-ton press with a 4inch diameter...

Thank you for the reply but it is still confusing. Even in your reply you make it sound like speed and velocity are the same? Could you explain it a bit with the values in the problem above? Also in a 400 meter doesn't everyone run... 400 meters?

1. A world-class sprinter accelerates to his maximum speed in 4.0s. He maintains this speed for the remainder of the 100-m race, finishing with a time of 9.1 seconds. Find A] What is the runners average acceleration during the first 4.0 seconds. 2. Vx=Vox+AxT X=Xo+VoxT+1/2AxT...

Crap! For some reason I was stuck on having to find the original velocity by finding the limit as time went down to zero... So I was plugging in 0.01, 0.001 and was getting ridiculous answers. Thank you! I've posted one more problem I cannot seem to get my head around.

1. A car sits on a freeway entrance ramp waiting for a break in traffic. The driver sees a gap and accelerates onto the freeway. Thar car starts from rest and moves in a straight line and has a speed of 20m/s when it reaches the end of the 120 m long ramp. Find A] acceleration of the car. B]...

1. An antelope moving with constant acceleration covers the distance between two points 70.0 meters apart in 7.00 seconds. It's speed as it passes the second point is 15 m/s. A] Find speed at first point. B] What is the acceleration? 2. From text University Physics 11th edition...

So no interference at all? Awesome, thank you.

I have a standard 8P8C modular jack (RJ45) and the small clip has broken off. Instead of cutting it off and re-wiring a new one I was interested to find out if I could attach magnets (how I will attach them is not important at this time) to the connector and have the magnets provide the...
