M_t = (T*w*t^2)/4.5
This formula uses 4 Variables

Variables Used

Torsional Moment in Crankweb - (Measured in Newton Meter) - Torsional Moment in Crankweb is the torsional reaction induced in the crankweb when an external twisting force is applied to the crankweb causing it to twist.
Shear Stress in Crankweb - (Measured in Pascal) - Shear Stress in Crankweb is the amount of shear stress (causes deformation by slippage along plane parallel to the imposed stress) in the crankweb.
Width of Crank Web - (Measured in Meter) - Width of Crank Web is defined as the width of the crank web (the portion of a crank between the crankpin and the shaft) measured perpendicular to the crankpin longitudinal axis.
Thickness of Crank Web - (Measured in Meter) - Thickness of Crank Web is defined as the thickness of the crank web (the portion of a crank between the crankpin and the shaft) measured parallel to the crankpin longitudinal axis.

STEP 1: Convert Input(s) to Base Unit

Shear Stress in Crankweb: 18.95 Newton per Square Millimeter --> 18950000 Pascal (Check conversion here)
Width of Crank Web: 65 Millimeter --> 0.065 Meter (Check conversion here)
Thickness of Crank Web: 40 Millimeter --> 0.04 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_t = (T*w*t^2)/4.5 --> (18950000*0.065*0.04^2)/4.5

Evaluating ... ...

M_t = 437.955555555556

STEP 3: Convert Result to Output's Unit

437.955555555556 Newton Meter -->437955.555555556 Newton Millimeter (Check conversion here)

FINAL ANSWER

437955.555555556 ≈ 437955.6 Newton Millimeter <-- Torsional Moment in Crankweb

Design of Centre Crankshaft

A crankshaft is subjected to bending and torsional moments due to the following three forces: (i) Force exerted by the connecting rod on the crank pin. (ii) Weight of flywheel acting downward in the vertical direction. (iii) Resultant belt tensions acting in the horizontal direction. In the design of the center crankshaft, two cases of the crank, positions are considered. They are as follows: Case I: The crank is at the top dead center position and subjected to maximum bending moment and no torsional moment. Case II: The crank is at an angle with the line of dead center positions and subjected to maximum torsional moment.

What is connecting rod?

The connecting rod is a connection between the piston and a crankshaft. It joins the piston pin with the crankpin. The small end of the connecting rod is connected to the piston pin and the big end to the crank pin. The purpose of the connecting rod is to convert the linear motion of the piston into the rotary motion of the crankshaft.
