Determine the following reaction and the TAC

A 1.0 meter long A36 steel rod with a diameter of 40mm is lightly attached at both end of the rod, end A and end B. A collar is located in the center of the rod. The initial temp is 60 degrees C. The final temperature is 35 degrees C. Determine the force that must be applied to the collar so that the reaction at B is zero.Given:Delta T=25 degrees CE for A36 steel: 200 GPaCoeff of thermal expansion: 12(10^-6)/degree C

If dC = 4.5 ft, determine (a) the reaction at A, (b) the reaction at E.

The rods of different materials are connected and placed between rigid supports at A and D, as shown in the figure. Properties for each of the three rods are given below. The bars are initially unstressed when the structure is assembled at 25°C. After the temperature has been increased to 90°C, determine:

An L-shaped structure is supported at A and D and subjected to two distributed loads and one concentrated load. Find: (1) RAX, the x-component of the reaction at A (2) RAy, the y-component of the reaction at A (3) RDx, the x-component of the reaction at D (4) RDy, the y-component of the reaction at D Flb w lb/ft w lb/ft Hft Lft Lft Lft Lft Answer all numeric solutions with five significant figures.
