If rod cd is rotating with an angular velocity cd = 4 rad/s, determine the angular velocities of rods ab and bc at the instant  = 70, bc is horizontal, and cd is vertical. [you are advised to use instantaneous center (ic) of zero velocity approach for link bc]

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

A175 g lump of molten lead at its melting point (327 c) is placed into 55.0 g of water at 20.0 c. the specific heat of lead is 130.j/kg c and the hf of lead is 20,400 j/kg. when the lead and the water have reached equilibrium, what is the temperature of the mixture?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.
