Concept explainers
(a) Point where crane’s 9500-kg counterweight be placed.
(b) Maximum load that can be lifted.
Answer to Problem 3P
Solution: (a) 2.26 m
(b) 4194.8 kg
Explanation of Solution
Given:
Mass to be lifted,
Formula Used:
To balance torque on any point on the vertical pillar,
Calculation:
For maximum mass M, we can place at extreme position i.e. at 3.4 m.
Conclusion: (a) Point where crane’s 9500 − kg counter weight should be placed is 2.26 m.
(b) Maximum mass that we can place is 4194.8 kg.
