Explanation:
Taking moment of forces about the hinge ,
moment of weight of man = 800 x p where p is his distance of man from hinge , in clockwise direction .
moment of tension force in rope in anticlockwise direction
= 500 x 3
For rotational balancing
800 x p = 500 x 3
p = 1.875 m .

Answer:
9.6 metersStep-by-step explanation:
Time taken by the tomatoes to each the ground
using h = 1/2 g t^2
t^2 = 2h/g = 2 x 50/ 9.8 = 10.2
t = 3.2 sec
horizontal ditance = speed x time = 3 x 3.2 = 9.6 meters
The question specifies the diameter of the screw, therefore the IMA of this screw is 0.812? / 0.318 = 8.02
