Hello guys, I am currently busy with this introductory assignment on Newtons Laws.
I have tried to solve but i am not sure whether i have the right solution.
Please help.
Three blocks are stacked on top of each other inside an elevator as shown in the figure.
Answer the following questions with reference to the eight forces defined as follows.
the force of the 3kg block on the 2kg block, F of 3 on 2,
the force of the 2kg block on the 3kg block, F of 2 on 3,
the force of the 3kg block on the 1kg block, F of 3 on 1,
the force of the 1kg block on the 3kg block, F of 1 on 3,
the force of the 2kg block on the 1kg block, F of 2 on 1,
the force of the 1kg block on the 2kg block, F of 1 on 2,
the force of the 1kg block on the floor, F of 1 on floor, and
the force of the floor on the 1kg block, F of floor on 1.
Assume the elevator is at rest. Rank the magnitude of the forces.
Rank from largest to smallest.
3kg block
V
2kg block
V
1kg block
v
elevator floor
F of floor on 1 and F 1 on floor (equal), F of 3 on 2 and F of 2 on 3 (equal), F of 2 on 1 and F of 1 on 2 (equal), F of 3 on 1 and F of 1 on 3 (equal).
Is this ranking right? Thanks
