The figure below (for illustrative purposes) shows a perfectly rigid (non-deformable) beam which is perfectly rigidly supported at points P and R by two force measurement scales, 1 and 2. PQ is 65 cm and PR is 150 cm. The beam is horizontal when each of scales 1 and 2 gives a reading of zero. Acceleration due to gravity is 9.81 ms.2 Scale 1 Point P Point Q Point R Scale 2 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 o calculate the answer) O A Reading of Scale 1= 150 kg: Reading of scale 2 - 65 kg OB. 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
