A uniform beam of mass M-100 kg and length 1 2.00 m is suspended from a ceiling at an angle of 30" below the horizontal. The beam is attached to the ceiling by a hinge at one end and a light support rope attached to the other end. What is the magnitude of the force by the hinge? (Enter your answer in units of N. Only enter the number using 2 significant figures.) 30 L = 2.0 m M=10.0 kg

A professor of mass m = 65 kg is seated on a light harness
connected to a rope and pulley system as shown. The professor's
feet touch a uniform plank of mass mplank = 20 kg which
is supported by a hinge at the wall. A mass M in a light bucket is
suspended from the right end of the plank. The professor is a
distance ℓ = 2.90 m from the hinge; the plank has length L...
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...

3) A uniform horizontal beam of length 12.0 m and a mass of 20 kg is attached to a wall. Its far end is suspended by a cable that makes an angle of 63 degrees with the beam. A person of mass 72 kg stands a distance d = 4.0 m from the wall. Find the tension in the cable as well as the magnitude and direction of the force exerted by the wall on the beam.
