3kNm. Sorry. Sent what I did to my lecture and he said it was right and he oppoligsed for teh strange number sin teh question that made me have answers that I thourght must be wrong. All sorted Cheers

Thanks. Wouldnt I need the friction to work out it angular momentem? P=ma x f So I am hoping I have done it correctly

Ah yes cheers. 810N Thanks Im rubbish at taking notes, scribble down as fast as I can go to keep up.

The fuel storage yard is separated from the main plate by a swingbridge (swinging in a horizontal plane). The motor driving the briudge has to swing through an angle of 90degrees in 120seconds. The bridge accelerates uniformly for 40s then moves at a constant velocity, decelerating uniformly to...

Question is A problem has arisen in teh goods yard where a large container is required to be pulled along a makeshift alipway. The container has a mass of 1.5tonne and is pulled along the horizontal slipway at an acceleration of 0.9m/s² by a rope wound around a winding drum. The resistance...

mv²/2 = 2(sx²/2) X= √mv²/2s 6000x7²/2x30000 - 4.9m Thanks soooo much!

Ah ok. Thanks √2x9.81x2.5 =7.00357 m/s

(Square route)2gh Would give me Velocity but how do I take into account slope?

I don't know what velocity I need to take for V in KE1 or KE2 do I? PE1 + KE 1 = PE2 + KE2 . There was me hoping there was a simple formula to use, I spent hours looking on net, no wonder I can't find one. Doh

PE1 - mgh KE1 - MV(Squared) PE2 - 0 KE2 - Same as PE1 Correct? How does this help tho?

Hi Question is- In the assesment of a buffers performance railway wagon of mass 6 tonne is allowed to roll freely down an incline of 1 in 20 Sine for a distance of 50M into a horizontal yard. At the end of yard is brought to rest by a pair of parrallel springs. The stiffness in each...
