Answer:
The maximum load the bar can withstand = 35.43 KN
Explanation:
Ultimate tensile strength of the given aluminium bar
= 540 M pa
Cross section area of the bar =
= 65.61 
We know that the ultimate strength of the bar is calculated from


= 540 × 65.61
= 35.43 KN
Therefore the maximum load the bar can withstand = 35.43 KN
Answer:
minimum radius of bend.
Explanation:
The sharpest bend that can be placed in a piece of metal without critically weakening the part is called the minimum radius of bend.
Answer:
• Gear ratios compare the output (or driven gear)
to the input (or drive gear)
• Gear Ratios can be determined using number
(n) of teeth on the gear or diameter (d) of the
gear
• If the output gear is larger than the
input gear the speed will decrease
• If the output gear is smaller than the
input gear the speed will increase
