A 74 kg rock climber has positioned himself as shown in the figure (with his hands on one side of a gap and his feet on the other side). Both friction and normal forces act on his hands and feet. The width of the gap, w, is 0.28 m and the climber's center of mass is a horizontal distance d = 0.44 m from the gap. The coefficient of static friction Hi = 0.46 between his hands and the rock...
Determine the moment of force about the point where a
bracket is attached to a wall. The bracket is shown in figure. It
extends 10 inches out from the wall and 5 inches up. A force of 35
lbf is applied to the bracket at an angle of 550 from the vertical.
The answer should be inft-lbf, so you need to do some conversions
of units. (Moment must be in foot-poundforce)

Problem 4 A traffic light hangs from a pole as shown in the figure. The uniform aluminum pole AB is 7.20 m long and has a mass of 12.0kg. The mass of the traffic light is 21.5kg. Determine (a) the tension in the horizontal massless cable CD, and (b) the vertical and horizontal components of the force exerted by the pivot A on the aluminum pole. 370 3.80 m
2. The shelf supports the electric motor which has a mass of 15 kg and mass center at Gm. The platform upon which it rests has a mass of 4 kg and mass center at Gp. Assuming that a single bolt B holds the shelf up and the bracket bears against the smooth wall at A, determine this normal force at A and the horizontal and vertical components of reaction of the bolt on the bracket. 200 mm 150 mm...

A 60 kg rock climber has positioned himself as shown in the figure (with his hands on one side of a gap and his feet on the other side). Both friction and normal forces act on his hands and feet. The width of the gap, w, is 0.24 m and the climber's center of mass is a horizontal distance d 0.54 m from the gap. The coefficient of static friction = 0.48 between his hands and the rock and 2...
A box of mass 21 -5 kg hangs from point B as shown in the Figure. The uniform aluminum pole AB is 7.50 m long and has a mass of 12.0 kg. Determine the magnitude of the tension force in the horizontal massless cable CD. Determine the vertical and horizontal components of the force exerted by the pivot A on the aluminum pole.
4. The block shown in figure 1 has mass m- 6.0 kg and lies on a fixed smooth frictionless plane tilted at an angle e 37.0 to the horizontal (a) Determine the acceleration of the block as it slides down the plane (b) If the block starts from rest 17 m up the plane from its base, what will be the block's speed when it reaches the bottom of the incline? (c) How much time elapses before it returns to...
4-610. The bracket is held to the wall using three A-36 steel bolts at B, C, and D. Each bolt has a diameter of 0.5 in. and an unstretched length of 2 in. If a force of 800 Ib is placed on the bracket as shown, determine how far, s, the top bracket at bolt D moves away from the wall. For the calculation, assume that the bolts carry no shear; rather, the vertical force of 800 lb is supported...
