For the data in Problem 4.7, investigate the effect of the base radius on the pressure angle. Choose two to three values of the base radius.
FIGURE 4.7 Cam with a roller inside a groove.
In the idealized model attached shown, m = 15 kg, k = 135 N/m, and the viscous damping ratio is 0.15. Assume that an external harmonic force F(t) = 15 cos 4 t acts on the system with F0=15 N and forcing frequency of 4 rad/s.
Helium is to be compressed from 120 kpa and 340 K to 700 kPa and 460 K. A heat loss of 20 kJ/kg occurs during the compression process. Neglecting kinetic energy changes, determine the power input required for a mass flow rate of 89 kg/min.
