A block of mass m1 = 5 kg rests on a table. Two ropes connect that block to two masses: one hangs off the left
A block of mass m1 = 5 kg rests on a table. Two ropes connect that block to two masses: one hangs off the left side of the table, and the other hangs off the right side. The coefficient of static friction s between the block and the table is 0.2. If one of the hanging masses has mass m2 = 3 kg, for what range of values of the other block's mass m3 will the system not move? Hint: What happens if m3 is very small? What happens if it is very big? Does this affect your force diagram in any way? How do you know what direction static friction will point? Does this depend on the sizes of the masses? You will need to think carefully about this, possibly making two diagrams depending on the direction of friction
