The figure shows a uniform, horizontal beam (length = 10.0 m, mass = 30.0 kg) that is held by a horizontal pin (pivoted at the wall), with its far end supported by a cable that makes an angle of 51 degree with the horizontal. A person of mass M stands 3.00 magnitude of 454 N. (a) Calculate the mass M of the person standing on the beam? (b) What are the horizontal and vertical components of the force the pin...
A uniform ladder of mass (m = 14.0 kg) and length (L) leans against a frictionless wall, see figure. If the angle θ = 60.0°, find the static friction force between the ladder and the floor when a 60.0-kg person stands two-third of the way up the ladder?
A uniform ladder of mass (m = 15.0 kg) and length (L) leans against a frictionless wall, see figure. If the angle θ = 52.0°, find the static friction force between the ladder and the floor when a 95.0-kg person stands two-third of the way up the ladder?
8. A uniform ladder of mass (m = 14.5 kg) and
length (L) leans against a frictionless wall, see figure.

ladder and the floor when a 80.0-kg person stands half way up the
ladder?

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.
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.
A uniform beam of length 10.0 m and mass 50.0 kg is attached to a wall at one end and free to pivot at this point. The beam is held horizontal by a cable attached to the far end of the beam and to a point on the wall 5.77 m above the pivot point. The angle between the beam and the cable is 30 degrees. A. What is the tension in the cable? B. What force is exerted by...
A uniform beam of length 20.0 m and mass 50.0 kg is attached to a wall at one end and free to pivot at this point. The beam is held horizontal by a cable attached to the midpoint of the beam and to a point on the wall 5.77 m above the pivot point. The angle between the beam and the cable is 30 degrees. A 20 .0 kg mass hangs from a second cable which is attached to the...
A uniform 35.5-kg beam of length ℓ = 5.60 m is supported by a vertical rope located d = 1.20 m from its left end as in the figure below. The right end of the beam is supported by a vertical column. (a) Find the tension in the rope. (b) Find the force that the column exerts on the right end of the beam. (Enter the magnitude.)
A uniform stationary ladder of length L = 4.2 m and mass M = 19 kg leans against a smooth vertical wall, while its bottom legs rest on a rough horizontal floor. The coefficient of static friction between floor and ladder is μ = 0.38. The ladder makes an angle θ = 53° with respect to the floor. A painter of mass 8M stands on the ladder a distance d from its base. a. Find the magnitude of the normal...
