1.Using the principle of transmissibility, the force F_evec can be slid along its line of action from point A to any other point along its line of action. What points along the line of action of the force F_evec would simplify the calculation of M, the magnitude of the total moment due to the force F_evec about point O?
2.Draw the influence line for the shear at point B. Plot numerical values every 5 ft. Assume the support at A is a roller and C is fixed. EI is constant.
3.Steam at 800 kPa and 300 C is bled off from a large supply line, passed through a valve, and allowed to enter an initially evacuated, uninsulated tank with a volume of 0.3 m3. When the pressure in the tank reaches 100 kPa, the valve is closed. The temperature in the tank when the valve is closed is reported to be 150 C. Determine whther this process is possible (Assume T0=25 C).
