(a) When rebuilding his car's engine, a physics major must continuously exert 3.74 ✕ 102 N of force to insert a dry steel piston as it slides into a steel cylinder. What is the normal force (in N) between the piston and cylinder? (Enter the magnitude.) I ALREADY SOLVED A AND GOT: 1246.67N. AND IT WAS CORRECT. NEED HELP WITH B. (b) What force (in N) would he have to continuously exert if the steel parts were oiled? (Enter the magnitude.)
