H.W/ By using ASD and LRFD methods, find a light section W12xw of A992 steel material of member BC in the figure below assumed the connection at the flange of two lines (6 %). Key of solution: The distance between A and C is 17.3 feet After analysis the forces.... BC-323.4 kip. 20¹ B 280' kip, 10⁰

In the assembly shown. the block has a weight w = 200 lbs and the cord is attached to the pin at B. The pulleys have radi of rt = 2 Tn. and r2 1 În. Neglect the mass of the pulleys and the link. Pulley Pulley A 45 12 Compute the reaction at the ĩnk AB In lbs." 250 260 280 B.

The figure shows a roof truss and the detail of the connection at joint B. Members BC and BE are angle sections with the thickness shown in the figure. The working stresses are 70MPa for shear in the rivets and 140MPa for bearing stress due to the rivets. How many 22mm diameter rivets are required to fasten the following members to the gusset plate: (a) BC; and (b) BE? 000 4 m B с 96 kN D 6 m E 200 KN 4 m F G 4 m 96 kN H to- PBC - -14-mm-thick gusset plate -13-mm-thick angle 6-mm-thick angle PBE

Part A If the required clamping force at the board A is to be 85 N, determine the torque M that must be applied to the handle of the "C" clamp to tighten it down. The single square-threaded screw has a mean radius of 10 mm, a lead of 3 mm, and the coefficient of static friction is u, = 0.35.
