The conveyor belt delivers each 20-kg crate to the ramp at A such that the crate's speed is 2.5 m/s, directed down along the ramp. The coefficient of kinetic friction between each crate and the ramp is 0.27 Assume that no tipping occurs. Take 0 30" (Elgure 1)

The t-component of the force F is known to be 90 KN. Determine the n-component and the magnitude Of F. n F. ww 20° 30°

Answer true or false in response to the following questions: (a) A force has zero moment about any point along its line of action. (b) A force has no moment about a line parallel to its line of action. (c) The magnitude of the moment of a force about a line equals the product of the component of the force perpendicular to the line and the distance between this component and the line. (d) The moment about a point P of the sum of a set of concurrent forces, placed at the point of concurrency (point P), equals the sum of the moments about P of the separate forces. (e) A couple has the same moment about any point. (f) If we know the moment of a couple about a point A, then we can find the moment of the couple about a specified line BC even if A does not lie on BC. (g) Two force and couple systems are equipollent if they have either the same resul- tant force or if the moments about some point P are the same for both systems. (h) It is possible for a system consisting of a single couple to…

If lengths a=5.9 m, b=2.3 m, c=3.4, and d=2.1, determine the angle (in degree) between the forces FB and FC. your answer must include 1 place after the decimal point.

D) Determine the true magnitude and direction of the forces acting on the cylinder

The two blocks A and B have a mass of 5.4 kg and 13 kg , respectively- (Figure 1) Figure 1'of 1

1: Determine the magnitude of F, and length y if F;=1500 N and x =1.75 m. You may assume that the tension in a rope on one side of a pulley is equal to the tension in the rope on the other side of the pulley. In making this assumption, you are neglecting the effects of friction. 2m
