Both pulleys are fixed to the shaft and as the shaft turns with constant angular velocity, the power of pulley a is transmitted to pulley b. the bearings are in proper alignment and exerted only force reactions on the shaft. note the positive direction of each axis.

a. determine the horizontal tension(t) in the belt on the pulley b if theta=0
b. determine the x, y,z components of the reaction at the journal bearing c(cx, cy, cz)
c. determine the x, y,z components of the reaction at the thrust bearing d(dx, dy, dz)

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
