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)

If a spring has a k value of 100 newtons per meter and it is stretched 0.50 meters, what is the restoring force of the spring?

What are the starting materials for nuclear fission? two small nuclei two large nuclei a neutron and a large nucleus a neutron and a small nucleus

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
