Each of the two vertical links CF connecting the two horizontal members AD and EG has a 10x40-mm uniform rectangular cross section and is made of a steel with an ultimate strength in tension of 400 MPa,while each of the pins at C and F has a 20-mm diameter and is made of a steel with an ultimate strength in shear of 150 MPa. Determine the overall factor of safety for the links CF and the pins connecting them to the horizontal members.
The assembly is used to support a distributed loading of w = 6.6 kN/m. The solid steel rod BC has a diameter of 13 mm and the steel pins at A, B and C have a diameter of 10 mm. The yield stress of the steel in tension is 250 MPa and in shear is 125 MPa. C 1.2 m 0.9 m 0.3 m Determine the factor of safety for the pin at B with respect to yielding? Input your answer to two decimal places.
The bell-crank mechanism shown below is supported by a single-shear pin connection at B and a roller support at C. A load P acts at an angle of θ=40° at joint A. The pin at B has a diameter of 0.375 in, and the bell crank has a thickness of 0.188 in. The ultimate shear strenght of the pin material is 28 ksi, and the ultimate bearing strenght of the crank material is 52 ksi. A minimum factor of safety of 3.0 with respect to shear and bearing is required. Assume that a = 9.0 in. and b =5.0 in. What is the maximum load P that may be applied at joint A of the bell crank?
Repeat Problem 11.2-3 assuming that R= 10 kN · m/rad and L = 2 m.
1. A solid square rod is cantilevered at one end. The rod is 0.8 m long and supports a completely reversing transverse load at the other end of 50 kN. The material is AISI 1060 hot-rolled steel (?? =370 MPa,?? =680 MPa ). Use a design factor of 2 and determine the dimensions of the square cross section for the following cases. Neglect any stress concentration. a. The rod must support this load for 100 cycles. b. The rod must support this load for 104 cycles. c. The rod must have infinite life.
Downvote for incorrect answer The connection is made using a bolt and nut and two washers. If the allowable bearing stress of the washers on the boards is (b)allow 2 ksi, and the allowable tensile stress within the bolt shank S is (allow 18 ksi, determine the maximum = allowable tension in the bolt shank. The bolt shank has a diameter of 0.31 in., and the washers have an outer diameter of 0.75 in. and inner diameter (hole) of 0.50 in.
