Bob has three bags connected by two ropes of equal strength. He pulls the bags on a rough horizontal ground towards the left as shown. Which rope will break first?
Here the rope 1 is withstanding 2 frictional forces ie., frictional forces between bag 2, bag 3 and sand. Rope 2 on the other hand withstands only 1 frictional force of that between bag 3 and sand. Therfore tension in the ropes are as shown below Rope 0 > Rope 1 > Rope 2 Since there is no mention of Rope 0 in the question Rope 1 is more likely to break among the 2.
Rope 1 as it has to drag both bag 2 and bag 3. Rope 2 only has to drag bag 3.
A wooden block of mass m resting on a rough horizontal table is pulled by a force F as shown in figure. If k is the Coefficient of friction between block and table. What will be its acceleration?
There are 2 bags filled with 25 pounds of potatoes each. The bag on the left is filled with small potatoes, while the bag on the right is filled with large potatoes. Which bag is bigger?
Two blocks are held against the wall by applying a horizontal force as shown in the diagram. The wall is frictionless but the surface between the blocks is rough.
Can these blocks remain in the equilibrium, answer with explanation?
