A round flange bearing is fastened to the machine frame by means of 4 cap screws. The angle made by central axis of bolt 2 and horizontal is θ. Also the radii of flange and pitch circle are a & b respectively. Given: Sum of squares of distance of bolts from axis of tilt is 2a² +b². Are all the four bolts under equal effective tensile load?

Also the radii of flange and pitch circle are a & b respectively. Given: Sum of squares of distance of bolts from axis of tilt is 2a² +b². Are all the four bolts under equal effective tensile load? Correct Answer No

All the bolts are at different distance from the axis of tilt and hence unequally loaded.
