A painter needs to climb d=1.2 m up a ladder (measured along its length from the point where the ladder contacting the ground), without the ladder slipping. The uniform ladder is 45 m long and weighs 328.03 N. It rests with one end on the ground and the other end against a perfectly smooth vertical wall. The ladder rises at an angle of theta=48.03 degrees above the horizontal floor. If the friction coefficient of the floor is 0.24. What is the weight of the painter? Use g = 10 m/s2 if you need to .
A 45.5‑kg box with the dimensions a×b (the width a = 0.6 m and height b = 1.3 m) is standing on a rough horizontal floor (μs = 1.3). A Professor wants to tip the box over, she pushes on the right side of the box with a horizontal force F = 140 N at a distance h = 1.04 m above the floor as shown in the picture below. The other forces acting on the box are the gravity force (applied to the CoM of the box), the static friction force Fs and the normal force N (both applied to the lower right corner of the box, point Q). Calculate the magnitude and direction of the torques produced by the forces acting on the box relative to the lower right corner (point Q). Assume uniform mass distribution. 1. The torque due to the external force, τQ(due to F) = 2. The torque due to the weight of the box, τQ(due to mg) = 3. The torque due to the friction force, τQ(due to Fs) = 4. The torque due to the normal force, τQ(due to N) =
The figure shows a 4.20-kg, 1.80-m-long rod hinged to a vertical wall and supported by a thin wire. The wire and rod each make angles of 45° with the vertical. When a 10.0-kg block is suspended from the midpoint of the rod, the tension T in the supporting wire is 49.3 N. The wire will break when the tension exceeds 75.0 N. 45° 45° T 10kg Tipler & Mosca, Physics for Scientists and Engineers, 6e © 2008 W.H.

A horizontal, uniform beam with a mass of 33.5 kg and a length ℓ = 5.80 m is suspended from a rope at a distance d = 1.20 m from its left end, while its right end is supported by a vertical column. A beam with a length of ℓ is suspended from a rope and supported by a vertical column. The rope is attached at a point that is a distance d from the left end of the beam. The column is beneath the right end of the beam. (a) Calculate the tension (in N) in the rope. N (b) Calculate the magnitude of the force (in N) that the column exerts on the right end of the beam.
The figure a shows a horizontal uniform beam of mass mo and length L that is supported on the left by a hinge attached to a wall and on the right by a cable at angle 0 with the horizontal. A package of mass mp is positioned on the beam at a distance x from the left end. The total mass is mp + mp = 56.5 kg.

The figure shows a horizontal beam of mass M = 22 kg and length L = 3.9 m supported at its left end by a frictionless pin and at the other end by an ideal cable attached to wall h = 1.6 m above the beam. A mass m = 9.7 kg is suspended from the beam a distance d = 1.6 m from the wall. Find the magnitude R of the "reaction force" exerted by the pin on the beam. h R = -d- m M L N
The drawing shows an A-shaped ladder. Both sides of the ladder are equal in length. This ladder is standing on a frictionless horizontal surface, and only the crossbar (which has a negligible mass) of the " A " keeps the ladder from collapsing. The ladder is uniform and has a mass of 15.2Kg. Det k mine the tension in the crossbar of the ladder.
A 400.0-N sign hangs from the end of a uniform strut. The strut is 4.0 m long and weighs 600.0 N.

A hungry bear weighing 85.0 kg walks out on a beam in an attempt to retrieve a basket of food hanging at the end of the beam. The beam is uniform, has a mass of 20.0 kg, is 8.00 m long, and pivoted at the wall; the basket weighs 10.0 kg. If the wire can withstand a maximum tension of 900 N, what is the maximum distance that the bear can walk before the wire breaks? ←x 60.0⁰ Goodies
