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

mistakes are ok

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
