A1000-kg object hangs from the lower end of a steel rod 5.0 m long that is suspendedvertically. the diameter of the rod is 0.80 cm and young's modulus for the rod is210,000 mn/m2. what is the elongation of the rod due to this object

m

Explanation:

= mass of the object = 1000 kg

= weight of the object hanged from rod = = = N

= length of the steel rod = 5 m

= elongation of length of the steel rod = ?

= young's modulus of steel = 210,000 MN/m² = 2.1 x 10¹¹ N/m²

= diameter of the rod = 0.80 cm = 0.0080 m

= Area of cross-section of rod = = = 50.24 x 10⁻⁶ m²

Using the equation

m

nah.   i'm just sleepy.

the force on the thing and the distance the force moves the thing
