Bro my physics exam had a typo and so the question was like “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? “this is simplified but the answer choices were 3.3403 Nero and stufff like that and none of them were even close to the real answer’!
