STEP 1: Convert Input(s) to Base Unit

Horizontal Force at Bearing1 by Tangential Force: 3443.57 Newton --> 3443.57 Newton No Conversion Required
Centre Crankshaft Bearing1 Gap from CrankPinCentre: 155 Millimeter --> 0.155 Meter (Check conversion here)
Length of Crank Pin: 42 Millimeter --> 0.042 Meter (Check conversion here)
Tangential Force at Crank Pin: 8000 Newton --> 8000 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_t = (R_h1*(b₁+l_c/2))-(P_t*l_c/2) --> (3443.57*(0.155+0.042/2))-(8000*0.042/2)

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.
