Extracted text: Determine the allowable value of force P (in Newtons), if a bar of diameter d = 39 mm and length L = 0.88 m is loaded in tension by force P. The bar has modulus E - 26 GPa and allowable normal stress of 149 MPa. The elongation of the bar must not exceed 3.0 mm. Answer in two decimal places. Numerical values only. Don't indicate units here, just on the submitted solution.
