Foucs more in thesecond part please. Name Assuming the pulley at E is of negligible radius,...
Assuming the pulley at E is of negligible radius, determine the moment M required for equilibrium of the 3 member pin connected frame. Remember from statics the tension in all parts of a rope or cable is the same. Also determine the normal stress in CD if its cross section area is 0.5 in and the shear stress in pin B ifit's diameter is 3/8" and is in double shear 2.5 3' D 300 lb 60° 60°
(3pts): The truss is constructed of A36 steel (E -2 a cross-sectional area of 250 mm2. Answer the following s 300 Clbe wna -250 MES, AI 00 G Pa and O, 250 MPa). All truss members have (a) Determine the normal stress and strain in member CD. (b) The support at joint D uses a pin placed in double shear. The pin diameter is 20 mm Determine the average shear stress acting in the pin. 50 kN 50 kN 25...
Problem 3: The wall crane supports a load of 700 lb with the pin at A and D. All pulleys are pin connected to the structure. The cross-sectional area of BD is 4 and the diameter for pulley B and C is 10 inches. 1) 2) 3) 4) Draw the FBDs of the pulley at E; Draw the FBD of the whole structure with the cable but without W; Find internal for NBD; Determine the average normal stress of BD...
2) (10 marks) a) The frame is subjected to the load of 4 kN which acts on member ABD at D. Determine the required diameter of the pins at D and C if the allowable shear stress for the material is tallow 40 MPa. Pins C is subjected to double shear, whereas pin D is subjected to single shear. b) Determine the preferred basic size for the pins at D and C. 3) (10 marks) A sign is subjected to...
