Support Rope 2.6 m Problem #3 (30 pts) A uniform strut weighing 100 N is hinged to a wall, is used to support an 800-N block as shown. The strut is 5 meters long and a support rope is attached to the far end of the strut and attached to the wall. The rope is held horizontally and keeps the far end of the strut 2.6 m away from the wall. (a) (10 pts) Draw the torque and fort diagrams...
The weightless strut in the figure below is not attached to the wall; it is prevented from falling only by friction. (Let w-395 N, L-4.85 m and h 3,05 m.) (a) Find the magnitude of the force of friction between the wall and the strut. (b) Find the normal force exerted by the wall on the strut. (c) Find the minimum coefficient of static friction
1.A playground merry-go-round has a radius of 3.0 m and a
rotational inertia of 600 kgˑm2. It is initially
spinning at 0.80 rad/s when a 20 kg child crawls from the center to
the rim. When the child reaches the rim the angular velocity of the
merry-go-round in rad/s is:
2.A picture P of weight W = 40 N is hung by two strings as
shown. The magnitude of the tension force
of each string is T and θ=30°. The...
A uniform horizontal strut weighs 280.0 N. One end of the strut is attached to a hinged support at the wall, and the other end of the strut is attached to a sign that weighs 190.0 N. The strut is also supported by a cable attached between the end of the strut and the wall. Assume that the entire weight of the sign is attached at the very end of the strut. Restaurane Find the tension in the cable (in...
A 12.0 m uniform beam is hinged to a vertical wall and held horizontally by a 5.00 m cable attached to the wall 4.00 m above the hinge, as shown in the figure below (Figure 1).The metal of this cable has a test strength of 0.900 kN which means that it will break if the tension in it exceeds that amount.
