3. A 30 kg, 2 meter long rod is sticking out from a building, and it is attached by a hinge. A 20 kg rock is hanging from the end of the rod. To keep the rod from rotating around the hinge (and the rock from falling) a long cable has been attached to the building 2 meters above the r and tied to the end of the rod. a. What is the tension in the cable? Hint, the rod's mass can all be assumed to be at the center of mass of the rod. b. What is the normal force of the building on the end of the rod? 2m 2m

Two concrete blocks weighing 320 lb each form part of the retaining wall of a swimming pool. Will the blocks be in equilibrium when the pool is filled and the water exerts the line loading shown?
The bar ABC is supported by three identical, ideal springs. Note that the springs are always vertical because the collars to which they are attached are free to slide on the horizontal rail. Find the angle at equilibrium if W = kL. Neglect the weight of the bar.
The uniform ladder of weight W is raised slowly by applying a vertical force P to the rope at A. Show that P is independent of the angle .
A 50 kg pole extends up a wall, making a 60° angle with the wall. The pole is supported by acable attached 3/4 of the way along the pole. This support cable is perpendicular to the wall.A 10 kg sign hangs from the end of the pole. The pole’s center of mass is 1/3 of the way fromthe wall to the end of the pole. (a) What is the tension in the cable?(b) What are the x and y components of the force the wall exerts on the pole?You must include an extended free body diagram showing all forces acting on the pole. Labelthe location on the pole you will use a reference for measuring distances (the “axis of rotation”) at the point where the pole touches the wall. Thank you!
The level of a common steelyard without hook connections weights 7kg and acts at 5cm to the left of the fulcrum. The hook which carries the load,weights 4kg and is also attached on the left-hand side of the fulcrum at a distance of 12cm.if graduation mark 72cm from the fulcrum reads 50kg. Find (a).the weight of rider (b). How far is the zero graduation from fulcrum (c).What is the movement of riderper kg of graduation?
A uniform horizontal strut weighs 425 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 235 N. The strut is also supported by a cable attached between the end of the strut and the wall. Assuming that the entire weight of the sign is attached at the very end of the strut, find the tension in the cable and the force at the hinge of the strut.

A sheep with a mass (m) 50 kg is hung on an animal scale system which consist of a helical spring of negligible mass. The stiffness (k) of the spring is 60 kN/m. During the hanging operation, the spring and the sheep are displaced vertically by 20 mm below the equilibrium position. 1.1. Draw a free body diagram and proof that a total length (L) of the scale system 2mg can be expressed as: L = k + Lo, where as Lo is the unstretched length of the spring. 1.2. Calculate the frequency of natural vibration of the system. 1.3. Calculate the velocity and acceleration of the sheep when it is 10 mm below the rest position.

A ski resort chair lift has towers spaced 44 m horizontaly appart. The upper tower is 15 m higher than the previous tower. If the chairs are 14 m horizontally appart and the first chair is 5 m past the lower tower what is the tension on both ends of the cable? The mass of each chair is 350 Kg and the height above the lower tower for each chair's attachment to the cable is 0.55624 m, 4 m, 9.33 m. Lower Tower Cable Tension = Upper Tower Cable Tension = KN. kN.
