A uniform cube of side length 5.9 cm rests on a horizontal floor. The coefficient of static friction between cube and floor is μ. A horizontal pull ?→P→ is applied perpendicular to one of the vertical faces of the cube, at a distance 5.3 cm above the floor on the vertical midline of the cube face. The magnitude of ?→P→ is gradually increased. (a) If μ is less than what value will the cube eventually begin to slide? (b) If μ is greater than what value will the cube eventually begin to tip? (Hint: At the onset of tipping, where is the normal force located?)

Problem 1: A meter stick has mass m = .2 kg (distributed uniformly along its length) and a length of (of course) 1 meter. The stick is placed simultaneously on two weight scales: one at the 20 cm mark (with 0 cm at the far left end of the stick), the other at the 70 cm mark, with no other supports or weights. Remember that a weight scale supplies an upward force, equal to the reading on the scale. Calculate the reading on both scales. Call the reading on the left scale (at 20 cm) FL, and the reading on the right scale (at 70 cm) FR. 20 cm 70 cm

A metal weight of mass 15 kg rests on a smooth (that is, frictionless) icy slope that makes an angle of 25° with the horizontal. It is attached to a rope that passes over a pulley at the top of the slope. The other end of the rope is attached to a crate of mass 12 kg that rests on a rough horizontal plank but irov odi is on the point of slipping along the plank. The coefficient of static friction between the crate and the plank is μ. metal weight 25° anolaups Tisda daiw alodasqyd sdt crate sib baa inol aino risa en't lo molisa planka) inabeup M etaduraszoq oda la coulev er no icy slope pulley inson oris 0-8-8-8 + f +vs otros sistensgeb-non pinos lo og oft sai toy, to todensee sobivora bm amizM sulau piuco Model the metal weight and the crate as particles, the rope as a model string ibal and the pulley as a model pulley.

V for vagsak. Two identical, uniform 1.50[m]- long beams weighing 150[N] each are connected at one end by a frictionless hinge. The beams are suspended from the ceiling by vertical wires such that they form a "V". A light horizontal crossbar is attached at the midpoints of the beams to maintain a specific angle between the beams. If the angle between the beams is 55.0°, what is the magnitude of the force exerted by the crossbar on each beam? Select one: O 156.2[N] 78.1[N] 214[N] 146.7[N]

A 1.5-lb slider is propelled upward at A along the fixed curved bar which lies in a vertical plane. If the slider is observed to have a speed of 10.6 ft/sec as it passes position B, determine (a) the magnitude N of the force exerted by the fixed rod on the slider and (b) the rate v at which the speed of the slider is changing (positive if speeding up, negative if slowing down). Assume that friction is negligible. 29 2.8' Answers: N = Ib i ft/sec?
A student of weight 675 N rides a steadily rotating Ferris wheel (the student sits upright). At the highest point, the magnitude of the normal force F→N on the student from the seat is 564 N. (a) What is the magnitude of F→N at the lowest point?
A fence post of mass m = 8 kg supports a fence with three lengths of barbed wire. The bottom wire is a distance d = 0.35 m from the ground and each wire is a distance 0.35 m above the previous one. Each of these three wires has the tension on it. For this problem, assume that the force exerted by these wires is purely horizontal. An additional guy wire is used to keep the pole upright with a tension of Fa = 490 N. The guy wire attaches to the post at a point h = 0.86 m above the ground and makes an angle of θ = 45 with respect to the horizontal. Write an expression for the tension in any one of the three fence wires. What is the normal force that the ground exerts upward on the post?
