Question 2 a) If a 500 N force F₁ is applied to the piston (as shown in Fig. Q2(a)) with 5 cm diameter, what is the magnitude of the force F2 that can be resisted by the piston with the 15 cm diameter? Neglect the weights of the pistons.

The bend has an angle of 30° and lies in a vertical plane. The volume of oil in the bend is 1.5 m³, and the empty weight of the bend is 5 KN. Assume the pressure along the centreline of the bend is constant with a value of 80 kPa gauge. Find the net force required to hold the bend in place.
