For the beam shown, calculate the shear and bending moment at points 6 ft and 16 ft from the left end using free-body diagrams.
A spherical buoy, having a diameter of 1.5 m and weighing 8500 N, anchored to the floor of a lake by a cable. Determine the force extorted by the cable, in N. The density of the lake water is 10^3kg^3/m^3 and g = 9.81m/s^2.
Suppose there is free trade between the islands in cloth and food but no trade in labor and land. Compute the equilibrium for the two islands together with the labor of Crusoe as the unit of account. (Hint: Use the symmetry of the problem.)
a 14 mm diameter 50 mm long mild steel rod undergoes a stress test. a tensile force of 18800 n is applied and the rod
a pulley is attached to the ceiling rafter and a single rope is passed over the pulley so that a 5kg body b is
Cortical bone gets weaker with aging, but it turns out that diaphyseal diameters can also change with aging, particularly in males, such that the safety factor of the diaphysis is approximately constant with aging.
Determine the two manometer readings, h and H. (ANS: 0; 0.252 ft)
