The radius of the 60-kg uniform disk is R = 500 mm. The space between the 80-kg mass and the vertical slot is lubricated, providing viscous damping with a damping factor of ζ = 0.15. If the couple M(t) = M0 sin ωt is acting on the disk, where M0 = 40 N · m and ω = 5 rad/s, determine the steady-state angular displacement θ (t) of the disk. Assume that the cable remains taut and does not slip on the disk.
What is the required bolt spacing s in the longitudinal direction if the shear force V = 110 kN (Note: Obtain the dimensions and moment of inertia of the W shape from Table E-1(b).
The combustion gases can be modeled as air behaving as an ideal gas. There is no significant heat transfer from the boiler to its surroundings. Assuming steady state and neglecting the effects of motion and gravity, determine
an ice skating rink is located in a building where the air is tair 20c and the walls are at tw 25c. the convection
Three lb of water is contained in a piston–cylinder assembly, initially occupying a volume V1 5 30 ft3 at T1 5 300°F. The water undergoes two processes in series: Constant-temperature compression to V2 5 11.19 ft3, during which there is an energy tra..
A turbine is fitted in the pipeline to recover the excess energy that is available, over that required to transfer the liquid from one vessel to the other. Estimate the power that can be taken from the turbine, when the liquid transfer rate is 500..
