A uniform horizontal beam of length 8 m and weight 200 N is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 53degree with the horizontal. If a cable is strong enough to withstand T= 1200 N how heavy person can walk to the end of the beam? When that person was at the 0.75 distance from the wall, find: a. the...
A uniform aluminum beam 9.0 m long, weighting 300 N rests symmetrically on two supports 5 m apart
A uniform aluminum beam 9.0 m long, weighting 300 N rests symmetrically on two supports 5 m apart. A boy weighting 600 N is standing initially at position x = 4 m to the right from support A a. Find the normal forces exerted by both supports on the beam b. Imagine now that the boy starts walking to the right along the beam. How far beyond the point B can the boy walk before the beam tips?
