A uniform bar of length 3.7 m and mass 4.8 kg 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 5.1 m which is also connected to the wall as shown above. What force in N does the wall exert vertically on the bar through the hinge? (Consider an upward force as positive and a downward force as negative.)

A uniform bar of length 3.9 m and mass 4.2 kg 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 5.1 m which is also connected to the wall as shown above. What is the tension in the rope in N?

Please explain how to derive
this and provide the answer.
A bar of length L and uniform density is held horizontally against a wall by a pivot at one end and a rope of tension T which pulls up and to the left making an angle θ with the vertical wall. The rope is attached to the bar at a distance l L from the wall. A mass M is resting at the end of the bar. If the bar...

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)

A flat, uniform board, which has mass 3.60kg and a length 0.50m, is held in a horizontal orientation by two vertical ropes. One rope is attached at the left end of the board and the other rope is attached at a point (3/4)L from the left end of the board. What force does the rope on the right exert of the board?

A uniform bar 7.5 m long is held against a rough wall by a light rope as shown in the diagram. The pulley may be assumed to be frictionless, W = 140 N and the weight of the bar is w = 40 N. Find (a) the tension in the rope attached to the bar, and (b) the minimum coefficient of friction between the bar and the wall if the bar does not slip. There is no hinge connecting the...

A uniform beam of mass and a length of, is attached to a wall by a pin connection. Its far end is supported by a cable that makes an angle of with the beam. A person of weight stands a distance from the wall. Find the tension in the cable and the magnitude and direction of the force exerted by the wall on the beam.
A uniform rod of mass M = 5.14kg and length L = 1.01m can pivot freely...
A uniform rod of mass M = 5.14kg and length L = 1.01m can pivot
freely (i.e., we ignore friction) about a hinge attached to a wall,
as seen in the figure below.
The rod is held horizontally
and then released. At the moment of release, determine the angular
acceleration of the rod. Use units of rad/s^2.
Determine the linear acceleration of the tip of the rod. Assume
that the force of gravity acts at the center of mass of...
