Answer to Problem 29P
Solution:
The horizontal and vertical forces exerted on upper hinge are
The horizontal and vertical forces exerted on lower hinge are
Explanation of Solution
Given:
Mass of the door ,
Formula used:
Equilibrium condition: the net force and torque would be zero.
Calculation:
Let
Let
Now taking sum of all the torques about hinge A
Conclusion:
The horizontal and vertical forces exerted on upper hinge are
The horizontal and vertical forces exerted on lower hinge are
