Answer to Problem 7PP
The efficiency of the ramp is
Explanation of Solution
Given data:
Input work on the crate,
Weight of crate,
Height of the ramp,
Formula used:
- Work Equation:
Where
- Efficiency Equation:
Where
Calculation:
As per the problem,
Weight of crate,
Height of the ramp,
To calculate the output work, substitute the values of force and distance in the work equation:
Now,
Substitute the values of input and output work in the efficiency equation:
Conclusion:
The efficiency of the ramp is
