Chapter 4, Problem 109P
The figure shows a schematic drawing of a vehicular jack that is to be designed to support a maximum mass of 300 kg based on the use of a design factor nd = 3.50. The opposite-handed threads on the two ends of the screw are cut to allow the link angle θ to vary from 15 to 70°. The links are to be machined from AISI 1010 hot-rolled steel bars. Each of the four links is to consist of two bars, one on each side of the central bearings. The bars are to be 350 mm long and have a bar width of w = 30 mm. The pinned ends are to be designed to secure an end-condition constant of at least C = 1.4 for out-of-plane buckling. Find a suitable preferred thickness and the resulting factor of safety for this thickness.

The layout of transmission shaft carrying two pulleys B and C and supported on bearings A and D is shown in Figure below. Power is supplied to the shaft by means of a vertical belt on pulley B, that is then transmitted to pulley C carrying a horizontal belt. The maximum tension in belt on pulley B is 2.5 kN. The angle of wrap for both the pulleys is 180o and the coefficient of friction 0.24. The shaft is made of plain carbon steel 30C8 (Syt=400 N/mm2) and the factor of safety is 3. Determine the shaft diameter on strength basis.
In the figure below the clamping force on the pipe is (331.7 lb), knowing that a single threaded screw Acme with major diameter (1 in) is used with coefficient of friction (0.2135).
