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 ladder stands on a rough floor and rests against a
frictionless wall as shown in the figure.
Since the floor is rough, it exerts both a normal force
N1
and a frictional force
f1
on the ladder. However, since the wall is frictionless, it
exerts only a normal force
N2
on the ladder. The ladder has a length of
L = 4.85 m,
a weight of
WL = 62.5 N,
