QUESTION:
(a) When rebuilding her car’s engine, a physics major must exert 300 N of force to insert a dry steel piston into a steel cylinder. What is the magnitude of the normal force between the piston and cylinder? (b) What is the magnitude of the force would she have to exert if the steel parts were oiled?
ANSWER:Solution 2PE Step-by-step solution Step 1 of 3 (a) When the piston is dry , major needs to apply 300N force. The force applied by major The friction force between the walls of the cylinder and piston The reaction force of the walls of the cylinder The kinetic friction coefficient between cylinder and piston The minimum force that is necessary to move the piston down is 300N that makes the psiton moves with constant velocity The applied force by the major is equal to the friction force on the walls
