Question
A box on a 15-degree incline weighs 350N. Given that the system is in static equilibrium and us = 0.55 and uk = 0.42.
a. what's the normal force (N) magnitude and what's its angle of direction with respect to the positive x-axis?
b. what's the frictional force magnitude and it's angle of direction with respect to the positive x-axis?
Now, a rope creates a tension T to pull the box in the direction 30 degrees upward with respect to the incline. This makes the box impending to slide.
c. what's the magnitude of T
d. what's the magnitude of N
