Question 71219: A worker tearing down a barn, uses a pinch bar 4 ft. long with the shorter end 2in. from the fulcrum. If the worker can excert a force of 150 lbs. at one end of the pinch bar, how great a force can he excert at the other end? (Note the differences in units, 2 in. and 4 ft. Units must be the same when using the lever formula.)
w1 d1 = w2d2
I'm lost after this. Can you help?
