Choose one of the following options that will give the correct readings of scales 1 and 2 when a mass of 30 kg acts vertically downwards at point Q. (The scales are not loaded to you will have to calculate the answer)
O A Reading of Scale 1 = 150 kg; Reading of scale 2 = 65 kg
O B. Reading of Scale 1 = 166.77 kg; Reading of scale 2 = 127.53 kg
O C. Reading of Scale 1 = 150 Newton; Reading of scale 2 = 65 kg
O D. Reading of Scale 1 = 166.77 Newton; Reading of scale 2 = 127.53 Newton
