1.A rigid open cylinder having an inside diameter of 15 mm contains a column of water 500 mm long at 20 degrees C. If a compressive force of 2 kN is applied to the top of the water column by a frictionless 15 mm piston, what will be the resultant water column height (mm)? Assume no leakage.
2.The two 100-mm-diameter spheres constructed of different metals are located in deep space. Determine the gravitational force which the copper sphere exerts on the titanium sphere if d=2m and d=4m.
3.Assume the actual water temperature for calibrating a 1/3 ft3 measure was 65 degrees F. If you had used a water temperature of 75 degrees F for your calibration, how much error would there be in your volume calculation (both in ft3 and as a percentage)
