Task 1 The Shaft Of The Crank Lever Is Loaded By Forces Through A Vertical Pin And Base Plate As Shown In Figure 1 The 1 (47.39 KiB) Viewed 15 times

Task 1 The shaft of the crank lever is loaded by forces through a vertical pin and base plate as shown in Figure 1. The pin is subjected to a vertical force of P kN at C. An axial thrust of Q kN is acting at D on the base plate which may be approximated as an equivalent axial force on the shaft AC and its other effect could be ignored. The shaft ac is Supported at end A & B. The yield strength of the shaft material is taken as 250 MN/m. 1)Evaluate the maximum principal stresses, minimum principal stresses and shear stress-induced in the shaft for the shaft diameter of 60 mm. (i)The factor of safety for the principal stresses obtained based on Tresca theory; (iii) The factor of safety for the principal stresses obtained based Von Mises - Henky theory, (iv)The maximum shear strain energy theory. (v)Discuss the answers with loads affected by forces through the vertical pin and base plate at A, B, C and D?
