The drawing shows a model for the motion of the human forearm in throwing a dart. because of the force m applied by the triceps muscle, the forearm can rotate about an axis at the elbow joint. assume that the forearm has the dimensions shown in the drawing and a moment of inertia of 0.065 kg . m2 (including the effect of the dart) relative to the axis at the elbow. assume also that the force m acts perpendicular to the forearm. ignoring the effect of gravity and any frictional forces, determine the magnitude of the force m needed to give the dart a tangential speed of 5.0 m/s in 0.10 s. starting from rest.

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)
