ROTATIONAL MOTION Quiz

• kg
• J
• m/s²
• N (newtons)

• All forces are zero
• Upward forces are greater
• Sum of upward forces equals sum of downward forces
• Forces cancel only horizontally

• It is too small
• It acts horizontally
• It is balanced by the floor
• Its line of action passes through G, so moment arm is zero

• Both reactions remain equal
• R₁ increases
• R₂ would increase and R₁ would decrease
• Both reactions become zero

• Because it is a large force
• Because it acts downward
• Because it is close to K₁
• Because it produces an anticlockwise rotation about G
