A V6, two-stroke cycle SI automobile engine has a 3.1203-inch bore and 3.45-inch stroke. The pistons have a height of 2.95 inches and diameter of 3.12 inches. At a certain point during the compression stroke piston speed in one cylinder is 30.78 ft/sec. The lubricating oil on the cylinder walls has a dynamic viscosity of Calculate the friction force on the piston under this condition. [lbf]
