Three small spherical masses are located in a plane at the positions shown below. Y (m) 4 3 2 1 0 -2 -3 S R -4 -5 -4 -3 -2 -1 8 1 X (m) 345 The masses are Q=0.800 kg, R=0.700 kg, and S=0.400 kg. Calculate the moment of inertia (of the 3 masses) with respect to an axis perpendicular to the xy plane and passing through x=0 and y=-3. [Since the masses are of small size, you can neglect the contribution due to moments of inertia about their centers of mass.] 28.8kg m^2

Obtain the values of vapor pressures of alcohol, water, and glycerin at a room temperature of 20 C.

A structural member with a rectangular cross section as shown in the accompanying figure is used to support a load of 2500 N. What type of material do you recommend be used to carry the load safely? Base your calculations on the yield strength and a factor of safety of 2.0.

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.
