Problem 2PE
(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
Step 1 of 3
a) We need to find out the normal force between the piston and the cylinder.
The coefficient of friction of steel on steel is .
The force exert to insert a dry steel piston into a steel cylinder is equal to the frictional force.
