Two ropes are used to hoist a 530 lb engine/transmission assembly as shown. The rope is anchored at C around the center part of the pin shown, causing the pin to experience a state of double shear. There is a frictionless pulley at A. The normal stress in the rope must not be allowed to exceed 15 ksi, and the shearing stress in the pin must not exceed 21 ksi. When the hoist is in the position given by: a = 44 in b = 11 ft c = 19 ft find the following: (a \& b) The forces carried in ropes AB and BC (c l& d) The necessary diameters of ropes AB and BC (e) The necessary diameter of the pin at C 2013 Michael Swanbom (a) TAB = (b) TBC = (c) dAB = (d) dBc = (e) d =
A rigid plate (AC) is connected to flat steel bars by pins at A and B. The horizontal flat steel bar ED is also connected via pins at points E and D. Member AE consists of two 6 mm by 25 mm parallel flat bars, while members EB and ED are single flat bars with dimensions 8 mm by 30 mm. If the structure is subjected to a 2-kip vertical force at point A, find the axial (normal) stress in members AE, EB, and ED. A 2 kip -3'- E B D -3'- C 4'
The rectangular bar shown is connected to a support bracket with a 24 mm diameter pin. The width of the rectangular bar is 70 mm and its thickness is 15 mm. The bearing stress in the bar cannot exceed 120 MPa. Determine the maximum value of Pmax that can be supported based solely on consideration of the bearing stress in the bar. Note: This question is not asking about any stresses in the support bracket...just bearing stress in the rectangular bar.
