1. The problem states: Calculate the work done when the moment applied is given by $$MA = 600 \times 1\text{ N.m}$$. 2. Since $$600 \times 1 = 600$$, the moment is $$600 \text{ N.m}$$. 3. Work done by a moment $$M$$ through an angle $$\theta$$ is calculated by $$W = M \times \theta$$, where $$\theta$$ is in radians. 4. However, the problem does not provide any angle $$\theta$$ through which the moment is applied, so we can only state the moment as $$600 \text{ N.m}$$. 5. If more information is given about the angle or displacement, work can be calculated. Thus, the moment or torque applied is $$600 \text{ N.m}$$ but the work done cannot be determined without the angle of rotation.
