A hoop with a mass of 3.04 kg is rolling without slipping along a horizontal surface with a speed of 7.33 m/s when it starts down a ramp that makes an angle of 27.35° below the horizontal. What is the forward speed of the hoop after it has rolled 3.12 m down as measured along the surface of the ramp? Give your answer in meters/second.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)

Ajoint produces movement when its angle decreases. which type of movement is it?

Part of a control linkage for an airplane consists of a rigid member cb and a flexible cable ab. if a force is applied to the end b of the member and causes it to rotate by θ = 0.5°, determine the normal strain in the cable. originally the cable is unstretched.
