The diagram illustrates two pairs of parallel forces, X and Y. Which statement is correct?
- AX is equivalent to a clockwise torque of $10\ \text{N m}$ and a force of $20\ \text{N}$ to the left.
- BX is equivalent to a clockwise torque of $20\ \text{N m}$ only.
- CY is equivalent to an anticlockwise torque of $30\ \text{N m}$ and a force of $20\ \text{N}$ to the left.
- DY is equivalent to an anticlockwise torque of $30\ \text{N m}$ only.
