Question 14 (10 Marks) A uniform rod that is 15 cm long and has a mass of 200 g is pivoted at one end and swings freely in a vertical plane. A clay ball with mass 20 g is attached to the free end of the rod. The rod and the clay ball together form a physical pendulum. Determine the period of oscillation of the system.

Solve the following system of equations algebraically: y = x^2 ?10x + 28 2x ? y = 4

Question 13 (6 Marks) A spring is attached to a horizontal pole. When a mass

is suspended from the spring, it stretches by 2.0 cm and reaches a new equilibrium position. The mass is then pulled down slightly and released, causing it to oscillate vertically. Determine the frequency of oscillation of the mass.

FLUIDSIM EXERCISES Create a Pneumatic Circuit using Fluidsim. A double-acting cylinder is controlled by three pushbuttons (Start_1, Start_2, Stop). The cylinder continuously extends and retracts when any of the Start buttons is pressed. Sensors LS1 & LS2 detect the positions of the cylinder when it is retracted or extended. Pressing the Stop button will stop the operation. But pressing any of the Start buttons again will resume the whole operation. Give the design.

QUESTION 1 A CO2 refrigeration unit works between the temperature limits of 25°C and -17°C. Calculate the following: 1.1. Ideal coefficient of performance. (3) 1.2. The mass of ice unit it can produce in one hour if it uses water at 15°C. The relative COP is 0.655, LI for ice is 305 kJ/kg and the power supplied is 115 kW.
