Take applied torque (1) = 25 kN.m, angle of twist (0) = 5 rad, modulus of rigidity (G) = 29 GPa, length (L) = 500 mm. swered arked out of 20 Flag estion Select one: O A. 31.92 mm B. 33.56 mm C. 32.48 mm D. 30.94 mm e foto

Answer 1

We know that T J = GO sold L Given that, da 22 mm T = 25kNom 9 @=5 rad G = 29 apa ,L=500mm

NOω, 32 Now 5.00 Hence opion c is correct. J = polar Moment of Inertia J = I 104_d") 25x103 x 103 *32 29x103 x 5 *(0"-d") 25X103 x103x32x500 Dadu 9x29x103 x 5 D4 - (2234 - 878096.237 a) D4 = 1112 352.237 6. D = 32.47 mm - >
plzzzz plzzzz plzzzzz upvote....thanks
