В A Cables AB and AC support a weight attached at joint A. The maximum allowable cable tension in either cable is 200 N. Find the maximum mass which may be supported, given: e = 65°, x.y,h = 3,4,5, respectively

A 200 N sign hangs from the middle of a cable between two buildings. The ends of each cable are attached to each building at the same height. The cable cannot exceed 1500 N without breaking. Find the minimum angle that the cable can make from the horizontal.

Question 2

One end of a 2.00 m uniform meter stick is placed against a vertical wall. The other end is held by a lightweight cord that makes an angle θ with the stick. The coefficient of static friction between the end of the meter stick and the wall is 0.530. What is the maximum value that θ can have if the stick is to remainin equilibrium?

A toddler weighs 10 kg and raises herself onto tiptoe (on both feet). Her feet are 8 cm long with each ankle joint being located 4.5 cm from the point at which her feet contact the floor. While standing on tip toe: (a) what is the upward normal force exerted by the floor at the point at which one of the toddler’s feet contacts the floor? (b) what is the tension force in one of her Achilles tendons? (c) what is the downward force exerted on one of the toddler’s ankle joints?

Chapter 12, Problem 034 In the figure, a thin horizontal bar AB of negligible weight and length L = 3.1 m is hinged to a vertical wall at A and supported at B by a thin wire BC that makes an angle e = 42° with the horizontal. A block of weight W = 250 N can be moved anywhere along the bar; its position is defined by the distance x = 1.75 m from the wall to its center of mass. Find (a) the tension in the wire, and the (b) horizontal and (c) vertical components of the force on the bar from the hinge at A.
