Answer: 0.235
Explanation:
Given data.
M1 = 0.91 Kg
M2 = 2kg
L = 0.95m
N = 35rpm
t = 10.44secs
Solution:
• we first solve for the center of gravity
•we calculate our moment of inertia
• we calculate the angular velocity
• we solve for our torque ( t )
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
Venus is closer, relatively the same size as the earth and has an atmosphere
