Two blocks of the same mass, m, are connected by a light string and rest on the slope and in the air, respectively (0<8<90). The friction force on the mass siting on the slope will be m zero upward along the incline the same magnitude with the tension in the string downward along the incline E none of above

The block of weight W is pulled by the force P inclined at the angle to the horizontal. Find the smallest force P and the corresponding angle that would cause impending sliding of the block. The angle of static friction between the block and the ground is s.

The woman is trying to move the crate of weight W by pulling on the rope at the angle to the horizontal. Find the smallest possible tension that would cause the crate to slide and the corresponding angle .

The center of gravity of the 3000-lb car is at G. The car is parked on an incline with the parking brake engaged, which locks the rear wheels. Find (a) the normal forces (perpendicular to the incline) acting under the front and rear pairs of wheels; and (b) the friction force (parallel to the incline) under the rear pair of wheels.

Q4/ Determine the magnitude of the mass (m) in the figure shown. Assume there is no friction in Each pulley, and the weights of all parts are small compared with the load. 20 kg

The spring clamp of Fig. block Fagainst the floor. The force in the spring is F = k(e – lo), where e is the present length of the spring, lo = 3 in. is the unstretched length of the spring, and k = 240 lb/ft is the spring constant. Determine all forces acting on mem- ber ÁBC of the spring clamp and the force exerted by the spring clamp on the block E. is used to hold the 8 in. D E 8 in. 6 in -6 in.- 6 in.

A uniform ladder of length 12 mand mass 30 kg rests with one ed on rough horizontal ground and the other end against a smooth vertical wall. The ladder is indined 65°. The coefficient of friction, H, between the ladder and the ground is 0.35. A woman of mass 65 kg is slowly dimbing up the ladder. She wants to know how far up the ladder she can dimb safely. Drawa diagramshowing all the force adting on the ladder when the woman is x metres fromthe foot of the ladder. (a) (b) Find the reaction of the ground on the ladder. (c) Show that the reaction of the wall on the ladder is less than 33.25g By taking moments about the base of the ladder, find how far up th ladder she an dimb safely. (d)
