Chapter 6, Problem 6.31QP
A concrete mix includes the following ingredients per cubic foot:
a. Cement = 25 lb
b. Water = 11 lb
c. No admixture
Table P6.31 shows possible changes that can be made to the mix ingredients. Indicate in the appropriate boxes in the table what will happen in each case for the workability and the ultimate compressive strength as increase, decrease, or approximately the same.

2–6. The square deforms into the position shown by the dashed lines. Determine the shear strain at each of its corners, A, B, C, and D, relative to the x, y axes. Side D′B′ remains horizontal.
The force P applied at joint D of the square frame causes the frame to sway and form the dashed rhombus. Determine the average normal strain developed in wire AC. Assume the three rods are rigid.
4. Draw a free body diagram of the loading and forces. Solve for the reaction A at
the wall support. Check your answer using the summation of forces.
