A 4.0- m-long iron bar of uniform cross section is held
perpendicular to the wall by a wire from the end of the bar to the
wall (see the figure). The bar is fastened to the wall with a
hinge. What is the tension in the wire if the iron bar weighs 700 N
and the wire is 5.0 m long?

In the figure, a bar of length L is attached by a frictionless hinge to a wall and held horizontal by a rope that makes an angle with the bar. The bar is uniform and has weight W. A mass of weight Wis suspended a distance x from the hinge. If the tension T in the rope equals 2W, x must be equal to: (Hint: use torques) T L O OL(sin 0-1) OL OL(2sin - 2)

You are a summer intern for an architectural firm. An
8.00-m-long uniform steel rod is to be attached to a wall by a
frictionless hinge at one end. The rod is to be held at 24.0 ?
below the horizontal by a light cable that is attached to the end
of the rod opposite the hinge. The cable makes an angle of 35.0 ?
with the rod and is attached to the wall at a point above the
hinge. 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 n, and a frictional force r, on the ladder. However, since the wall is frictionless, it exerts only a normal force N, on the ladder. The ladder has a length of L = 4.3 m, a weight of w. = 67.5 N, and rests against the wall a distance d...

A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. N2 mg d N. Since the floor is rough, it exerts both a normal force N, and a frictional force f, on the ladder. However, since the wall is frictionless, it exerts only a normal force N, on the ladder. The ladder has a length of L wall a distance d 3.75 m above the floor. If a person with a...

A uniform bar of length 3.2m and mass 4.4kg is attached to a
wall through a hinge mechanism which allows it to rotate freely.
The other end of the bar is supported by a rope of length 5.7m
which is also connected to the wall as shown above. What force in N
does the wall exert horizontally on the bar through the hinge?
(Consider a force to the right positive and a force to the left
negative.) see image below....
