Answer: The smallest effort = 300N
Explanation:
Using one of the condition for the attainment of equilibrium:
Clockwise moment = anticlockwise moments
900 × 1 = 3 × M
Where M = the weight of the strong man
3M = 900
M = 900/3 = 300N
Therefore, 300N is the smallest effort that the strongman can use to lift the goat
Answer:
Just over 300 N
Explanation:
Just over 300 N
Explanation: The goat is 1 meter from the fulcrum, and the strongman is 3 meters from the fulcrum. The mechanical advantage of the lever will be 3. The effort needed to lift the goat will be just over one-third the weight of the goat, in this case just over 300 newtons.
