3-39. A "scale" is constructed with a 4-ft-long cord and the 10-lb block D. The cord is fixed to a pin at A and passes over two small pulleys. Determine the weight of the suspended block B if the system is in equilibrium when s=1.5 ft
Body A in Fig. 6-33 weighs 102 N, and body B weighs 32 N. The coefficients of friction between A and the incline are µs =0.56 and µk =0.25. Angle θ is 40. Let the positive direction of an x-axis be up the incline. In unit-vector notation, what is the acceleration of A if A is initially (a) at rest, (b) moving up the incline, and (c) moving down the incline.
As shown in Fig. 4–70, five balls (masses 2.00, 2.05, 2.10,
2.15, 2.20 kg) hang from a crossbar. Each mass is sup-
ported by "5-lb test" fishing line which will break when
its tension force exceeds 22.2 N (= 5.00 lb). When this
device is placed in an elevator, which accelerates upward,
only the lines attached to the 2.05 and 2.00 kg masses do
not break. Within what range is the elevator's acceleration?

The static coefficients of friction between his shoes and the wall, and between his back and the wall, are 0.80 and 0.60, respectively. What is the minimum normal force he must exert? Assume the walls are ver- tical and that the static friction forces are both at their maximum. Ignore his grip on the rope.
