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...

A rigid, uniform, horizontal bar of mass m1 and length L is
supported by two identical massless strings. (Figure 1) Both
strings are vertical. String A is attached at a distance d<L/2
from the left end of the bar and is connected to the ceiling;
string B is attached to the left end of the bar and is connected to
the floor. A small block of mass m2 is supported against gravity by
the bar at a distance x from...
A uniform bar of length 3.9 m and mass 4.2 kg is attached to a wall...
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?

A fish is supported by a cable attached to
a long, uniform rod that can pivot at the base as shown
in the figure. A cable provides a tension force at the top of the
pole and makes an angle of with the horizontal. The rod has a mass
of and makes an angle of with the ground.
a) What is the magnitude of the tension in the cable?
b) What is the magnitude of the x-component of the force

Problem 6: A uniform beam of length L = 3.2 m and mass M = 32 kg has its lower end fixed to pivot at a point P on the floor
Problem 6: A uniform beam of length L = 3.2 m and mass M = 32 kg has its lower end fixed to pivot at a point P on the floor, making an angle θ = 29° as shown in the digram. A horizontal cable is attached at its upper end B to a point A on a wall. A box of the same mass Mas the beam is suspended from a rope that is attached to the beam one-fourth...

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 uniform board of length 2.40 m and mass 4.00 kg is pivoted at
one end and has a rope attached at the other end, as shown in the
figure below. A bucket of mass 2.00 kg is suspended 40.0 cm from
the rope. Find: (a) the tension in the rope; (b) the horizontal and
vertical forces exerted by the pivot.

A 10200-N shark is supported by a rope attached to a 3.40-m rod that can pivot at the base. A rod is attached to a pivot at the base of a wall on the left. The rod extends up and right at a 60.0° angle from the horizontal. A cable connected to the top end of the rod extends up and left at a 20.0° angle from the horizontal before connecting to the wall. A shark hangs from a rope at the top...
