Calculate the value of the coefficient of friction using the data: F=24 N, Normal force=12 N.(a) 2(b) 4(c) 8(d) 9The question was asked in an interview for internship.This interesting question is from Nature of Traction Load topic in chapter Traction Drives of Electric Drives

Answer»

Right option is (a) 2

The best I can EXPLAIN: Coefficient of friction is the RATIO of the friction FORCE and normal force. It is dependent on the smoothness of the SURFACE area. μ=24÷12=2.
