# M1 statics help watch

1. Hi could anyone offer any advice on how to answer part c of this question?
Answers so far a) 23N b) 17.6N
With part c i know i my mind that it is equilibrium because the maximum value for friction is greater than the 2.5gsin20 of weight but im unsure how to show this in an exam??

Work out the component of the weight acting down the plane and the maxium frictional force, and then:

"Weight down plane is ...N and since this is less than the maximum frictional force of ...N, the particle remains in eqilibrium".

Okay thanks, so i should just explain it to the examiner with a short sentence.
