The slotted arm OA rotates about a fixed axis through O. At the instant under consideration, θ = 20°, θ˙ = 50 deg/s, and θ¨ = 21 deg/s2. Determine the magnited of the force F applied by arm OA and the magnitude of the force N applied by the sides of the slot to the 0.4-kg slider B. Neglect all friction, and let L = 0.42 m. The motion occurs in a vertical plane

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

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
