Determine the average shear stress developed in pins A and B of the smooth two-tine grapple that supports the log having a mass of 3 Mg. Each pin has a diameter of 25 mm and is subjected to double shear. A 20 B E C D + c ©F y = 0; 2(F sin 30°) - 29.43 = 0 F = 29.43 kN 0.2 m a+©M E = 0; P cos 20°(0.2) - (29.43 cos 30°)(1.2) + (29.43 sin 30°)(0.4 cos 30°) 1.2 m = 0 P = 135.61 kN t A = t B = V 135.61(10 3 ) A = 2 p 4 (0.025)2 = 138 MPa Ans. 30 0.4 m 30 *1–48. The beam is supported by a pin at A and a short link BC. If P = 15 kN, determine the average shear stress developed in the pins at A, B, and C. All pins are in double shear as shown, and each has a diameter of 18 mm.
