Two circular rods, one steel and the other copper, are both 0.780 m long and 1.50 cm in diameter. each is subjected to a force with magnitude 4350 n that compresses the rod. what is the difference in the length of the two rods when compressed?

The difference in the length of the two rods when compressed is .

Explanation:

Given that,

Length = 0.780 m

Diameter = 1.50 cm

Force = 4350 N

(a). For steel rod

We know ,

The young modulus for steel rod

Using formula of young modulus

(b). For copper rod

We know ,

The young modulus for steel rod

Using formula of young modulus

The difference in the length of the two rods when compressed is

Hence, The difference in the length of the two rods when compressed is .

the average speed is 24.57 km/hr
