Chapter 18, Problem 4P
In Chapter 12, we explained that the electric power consumption of various electrical components can be determined using the following power formula: P = VI = RI2 where P is power in watts, V is the voltage, I is the current in amps, and R is the resistance of the component in ohms.
Plot the power consumption of an electrical component with a resistance of 145 ohms. Vary the value of the current from zero to 4 amps. Discuss and plot the change in power consumption as the function of current drawn through the component.

An oil pipeline and a 1.200 m^3 rigid air tank are connected to each other by a manometer, as shown in the figure. The tank contains 15 kg of air at 80°C. Assume the pressure in the oil pipeline to remain constant and the air volume in the manometer to be negligible relative to the volume of the tank. Determine the change in Δh when the temperature in the tank drops to 20°C.

- In excavation for a wall footing, the water table level was lowered from a depth of 1.0 m to a depth of 3.0 m in a clayey soil deposit. Considering that the soil has a water content of 28% when it is fully saturated, and above the water table the (dry) unit weight of the soil is 17 kN/m³. Assuming initially that all of the soil above the water table is dry, then compute the following: 1. The effective stress at a depth of 4.0 m after the lowering of the water table. Take Gs = 2.68. (Hints: w*Gs=Sr*e) 2. The increase in effective stress at a depth of 5 m. (You also need to plot the values of total vertical stress and effective vertical stress against depth before and after lowering the water table.)arrow_forwardCalculate the collapse load (P) for the two fixed ended beam shown below.
