Question

A bar of length 5 m is subjected to an axial tensile load of 100 KN. The bar is 25 mm diameter for 2

m of its length, 30 mm diameter for 1 m of its length, and 20 mm diameter for the remaining 2 m of

its length. Taking E = 2 x 105 N/mm2

. Calculate the total increase in length of the bar.​

Answer 1

Answer:

In physics, the Planck length, denoted ℓP, is a unit of length. It is also the reduced Compton wavelength of a particle with Planck mass. It is equal to 1.616255(18)×10−35 m.It is a base unit in the system of Planck units, developed by physicist Max Planck. The Planck length can be defined from three fundamental physical constants: the speed of light in vacuum, the Planck constant, and the gravitational constant.
