Question

A cable that can support a load W is cut into two equal parts. The maximum load that can be supported by either part is

• A. W
• B. $\frac{W}{2}$
• C. $\frac{W}{4}$
• D. 2W

Answer 1

The correct option is A W

When the cable is cut into two equal parts, then maximum load that can be supported by either parts of the cable remain the same as before. Since,

$Breakingstress=\frac{F}{A}$

Where, F is the force and A is the area of cross section.

Breaking is independent of length of cable. So, load remains the same when a load W is cut.
