A six-cylinder IC engine has a 6.00-cm bore, a 5.78-cm stroke, and a connecting rod length of 11.56 cm. In the power stroke of the cycle for one cylinder at a crank position of 90° aTDC, the pressure in the cylinder is 4500 kPa and the sliding friction force on the piston is 0.85 kN. Piston acceleration at this point can be considered zero.

Calculate:

(a) Force in the connecting rod at this point. [kN] Is it compressive or tensile?

(b) Side thrust force on the piston at this point. [kN] Is it on the major thrust side or the minor thrust side?

(c) Side thrust force on the piston at this point if the wrist pin is offset 2 mm to reduce the side thrust force. (Assume rod force and friction force are the same as above.) [kN]
