A flywheel weighted 1000 N is attached in the middle of the shaft and tensions of 300 N and 600 N are applied on the pulley at the right end of the shaft (see below picture). The shaft is made of SS400 steel and has yield strength Sy 240 MPa. You can refer to Chapter 5 for moment and deflection equations. Find: 1. Bending stress (ob) maximum on the shaft 2. Torsion stress (T) on the shaft 3. Minimum shaft diameter, if the safety factor is 1.5 Find 500 mm 500 mm 100 mm 300 N 600 N

A beam has a bending moment of 3.5 kN-m applied to a section with a hollow circular cross-section of external diameter 3 cm and internal diameter 2.3 cm . The modulus of elasticity for the material is 210 x 109 N/m2. Calculate the radius of curvature and maximum bending stress. Also, calculate the stress at the point at 0.6 cm from the neutral axis (i) The moment of inertia in (mm^4)=  ii) The radius of curvature in (mm) = (iii) The maximum bending stress  in (N/mm^2)= iv) The bending stress at the point 0.6 cm from the neutral axis  in (N/mm^2)=

es A gear reduction unit uses the countershaft shown in the figure. Gear A receives power from another gear with the transmitted force FA applied at the 20° pressure angle as shown. The power is transmitted through the shaft and delivered through gear B through a transmitted force Fg at the pressure angle shown. For the steel countershaft specified in the table, find the deflection and slope of the shaft at point A. Use superposition with the deflection equations in Table A-9. Assume the bearings constitute simple supports. In the figure below, FA is 310 lbf and the diameter of the shaft (dshaft) is 1.29 in. dshaft Gear A 20-in dia. 16 in FA 20⁰ The deflection at point A is The slope at point A is 14 in 100 Gear B 8-in dia. rad. 9 in in.
