Asteel rod with a length of l = 1.55 m and a cross section of a = 4.45 cm2 is held fixed at the end points of the rod. what is the size of the force developing inside the steel rod when its temperature is raised by ∆t = 37.0 k? the coefficient of linear expansion for steel is α = 1.17×10-5 1/k, and the young modulus of steel is e = 200.0 gpa.

To solve this problem it is necessary to apply the concepts related to thermal stress. Said stress is defined as the amount of deformation caused by the change in temperature, based on the parameters of the coefficient of thermal expansion of the material, Young's module and the Area or area of the area.

Where

A = Cross-sectional Area

Y = Young's modulus

= Coefficient of linear expansion for steel

= Temperature Raise

Our values are given as,

Replacing we have,

Therefore the size of the force developing inside the steel rod when its temperature is raised by 37K is 38526.1N

show the diagram then i will answer

he . if i may ask what i your question exactly?
