Question
Three blocks are stacked on top of each other inside an elevator as shown in (Figure 1) .
Answer the following questions with reference to the eight forces defined as follows.
the force of the 3 kg block on the 2 kgblock, F3on2,
the force of the 2 kg block on the 3 kgblock, F2on3,
the force of the 3 kg block on the 1 kgblock, F3on1,
the force of the 1 kg block on the 3 kgblock, F1on3,
the force of the 2 kg block on the 1 kgblock, F2on1,
the force of the 1 kg block on the 2 kgblock, F1on2,
the force of the 1 kg block on the floor, F1onfloor, and
the force of the floor on the 1 kg block, Fflooron1.
Assume the elevator is at rest. Rank the magnitude of the forces.
Rank from largest to smallest. To rank items as equivalent, overlap them.
Explanation / Answer
here the forces from largest to smallest is
1. F(1 on the floor) & F(floor on 1)
2. F(1 on 2) & F(2 on 1)
3. F(2 on 3) & F(3 on 2 )
4. F(3 on 1) & F(1 on 3)
Force,F1,of 3kg block on the 2kg block,F of 3 on 2=3*9.81= 29.43N
Force, F2, of 2kg block on the 3kg block, F of 2 on 3=3*9.81= 29.43N
Force,F3 of 3kg block on the 1kg block, F of 3 on 1=0N(not in contact)
Force,F4 of the 1kg block on the 3kg block, F of 1 on 3, = 0 N
Force,F5 of 2kg block on 1kg block,F of 2 on 1=29.43+2*9.81=49.05 N
Force,F6 of the 1kg block on the 2kg block, F of 1 on 2, = 49.05N
Force,F7 of the 1kg block on the floor, F of 1 on floor, and =58.86 N
Force,F8 of the floor on the 1kg block, F of floor on 1= 58.86N
Gravitational forces between blocks are neglected.
Magnitudes of all forces are ordered as F7 >F5>F1>F3
