y Nou А Х The figure above shows a point mass riding up-and-down along a sinusoidal curve. The curve estimates the position of the particle, (x, y), travelling on a surface with waves. The mass is constrained to ride along this curve such that y(x) = sin(x) Gravity acts in the negative y - direction. 1. Write down the virtual work done by gravity in terms of dy e.g. Foy 2. What is the virtual work done by gravity in terms of 8x e.g. F8x?
