Exercise: A machine is mounted on a light rigid beam AB supported by two springs as shown in Fig. 4.7. The spring at A has stiffness 20 kN/m, and that at B 60 kN/m. As a result of the machine's action and location, a vertical force Fe 4.8 kN is applied at C. If the beam is initially horizontal, what is the deflection at C when force F is applied and what is the energy stored in each spring?

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
