Extracted text: 19 If the ratio of the velocity of outward stroke and velocity of return stroke is 8, then the ratio of outward angle to return angle is 361 O a. 2 O b. 0.125 Oc. 8 Od. 4 20 Find the correct statement with respect to balancing of masses: Oa. Unbalanced force due to reciprocating masses varies in direction but constant in magnitude O b. Unbalanced force due to reciprocating masses varies in magnitude but constant in direction O c. Unbalanced force due to rotating masses is constant in magnitude and direction O d. Unbalanced force due to rotating masses is constant in direction but varies magnitude
