The centre of gravity of the assembly.
Answer to Problem 8.92P
The centre of gravity of given part is
Explanation of Solution
Given Information:
Small screws are used to fasten a piece of hardwood to the bracket that is formed from 1/20-in.-thick steel sheet metal as shown in figure below,
For steel,
Calculation:
Consider the following assembly,
Part | |||||
1 | Steel Plate | 0.00 | |||
2 | Steel Plate | 0.00 | |||
3 | Steel Plate | ||||
4 | Wood |
Prepare the following table considering
Part | ||||||||
1 | Steel Plate | 0.64 | 3.75 | 0.00 | 3.00 | 2.39 | 0.00 | 1.91 |
2 | Steel Plate | 1.11 | 3.75 | 5.25 | 0.00 | 4.18 | 5.85 | 0 |
3 | Steel Plate | 0.32 | 3.75 | 10.50 | 1.50 | 1.19 | 3.34 | 0.47 |
4 | Wood | 1.96 | 3.75 | 9.00 | 1.50 | 7.34 | 17.62 | 2.93 |
Total |
Now calculate the centre of gravity as,
Conclusion:
Therefore, the centre of gravity of given part is
