(a) (i) (ii) A allocated for a uniform rod. (iii) Explain how to determine centre of gravity of a body with irregular shape. (b) Given the figure below. Calculate the reaction R1 and R2 due to weight. +R1 Define centre of gravity of a body. Explain how centre of gravity is 14 4-5cm- 200cm. 90N -100cm- R₂ -150cm 150 B
