A block weighing 50 kg is pressed against a vertical wall with a force of 100 N directed perpendicular to the wall. What vertical force is required to move the bar up the wall evenly? The friction coefficient is 0.3
The friction force is 30N, the gravity is 500N. In total 530N.
Both of them are directed downward, against the direction of movement, which means that in order to move the bar up, a force of 530N is enough.
Answer: 530N.
