Mass of the man, 
Radius of the rod, 
Original length of the rod 
Distance between iron atoms in steel, 
Step-by-step explanation
Step 1.
The force acting on the rod is because of the weight of the man.
Therefore, use the relation
, where F is the force acting on the rod 
, A is the cross-sectional area of the rod, E is the Young’s modulus of steel and 
is the change in length of the rod
