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

Answer 1

Answer: (C)

$W$

Answer 2

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, Breaking stress $=\frac{ F }{ A }$ 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.
