The structure shown consists of five pin-connected members

Question

1. The structure shown consists of five pin-connected members (members AC and BD do not intersect). In addition to the 4kip force shown, the individual members of the structure have the weights listed in the table. Idealize the structure to be a truss and determine the forces supported by each member using the method of joints.

Member	Weight, lb
AB	400
AC	100
BC	200
BD	100
CD	400

2. The top chord of the steel truss is subjected to the load shown. The truss has support reactions A_y, M_x, and M_y from a roller at A and a pin at M. Determine the force supported by member FH using the method of sections. All angles are 60°.

3. A metal bottle cap opener is shown. If a vertical force of 10N at point A is required to remove a bottle cap, determine the internal forces that develop on cross section D.

4. A 5° steel wedge is used to level a 10ft long uniform steel beam AB weighing 400lb. The ends of the beam are supported by concrete walls D and E. Determine the force needed to drive the wedge to the left, and describe the motion of the beam that results (if end B of the beam is lifted or if the entire beam slides to the left). The coefficients of static friction are 0.4 for steel-on-steel contact and 0.3 for steel-on-concrete contact.

5. A rectangular area with base b and height h, and centroid at point C is shown. Determine the area moments of inertia I_x and I_x'.

Answer 1

Please consider the tables, diagrams and information provided in the assignment illustrated above. On the basis of all that things, please respond accordingly in an appropriate manner. Q1. The structure illustrated comprises of 5 pin-connected members. Moreover to the 4kip force illustrated, the individual members of structure encompass the weights listed in the table. Idealize the structure to be a truss and find out the forces supported by each member employing the method of joints. Q2. The top chord of steel truss is subjected to the load illustrated. The truss has support reactions Ay, Mx and My from a roller at A and a pin at M. Find out the force supported by member FH employing the technique of sections. All angles are 60°. Q3. A metal bottle cap opener is illustrated. If a vertical force of 10N at point A is necessary to take away a bottle cap, find out the internal forces which build up on cross section D.
