Describe Pascal’s law?

Find the relationship between 8₁, the elongation of rod (1), and the internal tensile force, F₁, in rod (1). Assume 8, is a positive value in units of mm and F₁ is a positive value in units of kN. So, the answer you enter for the ratio (8₁/F₁) must be in units of ( mm/kN). 8₁ F₁ = i ! mm/kN

At higher temperature, strength and strain hardening are increased, whereas, ductility is decreased which permits greater plastic .deformation True O False O .The strength constant (C) is increased with increasing of temperature True O False O The metal is becoming weaker as strain increases, this is because of .strain hardening (work hardening) property نقطة واحدة True O False O The engineering stress and strain are defined relative to the .instantaneous area and length of test specimen True O False aaly ihi In sheetmetal working processes, the surface area-to-volume ratio of .w.p. is low True O False ialy ihii Determine the value of the strain-hardening exponent for a metal that will cause the average flow stress to be 70% of the final flow stress after .deformation 0.444 0.421 0.422 0.428 aals i For pure copper (annealed), the strength coefficient = 330 MPa and strain-hardening exponent = 0.52 in the flow curve equation.
