Q4: Design a scissor jack Power Screw for Fig. (A) and Fig. (B) made of (1035 hot rolled Carbon Steel) to lift a 1300kg car. Calculate what stresses are on and power screw .Determine tl size and pitch that will withstand the force (based on the shear stress only i.e. neglect the axial stress and torsional stress), use a proper failure theory) at lowest point (15 degrees) to highest (70 degrees). If the collar has (a) sliding friction, (b) rolling friction. Assume the coefficients of friction.
