The correct option is (a) Revolving mass

Explanation: Each imaginary secondary crank with a mass attached to the crankpin is inclined to the line of stroke at two times the angle of the actual crank. The values of the secondary forces and couples can be obtained by considering the revolving mass.

In a steam engine, one method of obtaining the earlier cut-off with a simple slide valve may be obtained by increasing the angle of advance of the eccentric but reducing the throw of the eccentric and keeping the steam lap and exhaust lap constant. The method will cause withdrawing or throttling of steam.
