Diameter of side crankshaft at juncture of crankweb for max torque Formula

What is crank web?

A crank web is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft or a separate arm or disk attached to it. Attached to the end of the crank web by a pivot is a rod, usually called a connecting rod. Almost all reciprocating engines use crank web (with connecting rods) to transform the back-and-forth motion of the pistons into rotary motion. The crank webs are incorporated into a crankshaft.
