Rigid bar BCD is supported by a pin at C and by aluminum rod (1). A concentrated load P is applied to the lower end of aluminum rod (2), which is attached to the rigid bar at D. The cross-sectional area of each rod is A = 0.20 in.2 and the elastic modulus of the aluminum material is E

= 10900 ksi. After the load P is applied at E, the strain in rod (1) is measured as 1350 με (tension). Assume L1=44 in., b=18 in., a=30 in., and L2=105 in.

Determine the magnitude of load P.

Determine the total deflection of point E relative to its initial position.
