Q.2 If the (010×10) cylinder compressive strength of O.P.C. concrete at 10-day is (14 MPa). Calculate (20×20×20) cube comp. strength at age of 28 days.

Draw the shear and moment diagrams for the beam shown. After you have the diagrams, answer the questions. The distance x is measured from point A to the right. 300 lb/ft 7.2₁4.0' Questions: At x = 2.8ft, V = At x = 8.5ft, V= i i lbM = lbM = i i

Use the graphical method to construct the shear-force and bending-moment diagrams for the beam shown.  Let a = 3.2 ft, b = 9.6 ft, c = 3.6 ft, MA = 6700 lb·ft, P = 3000 lb, and w = 660 lb/ft.  Label all significant points on each diagram and identify the maximum moments (both positive and negative) along with their respective locations.  Clearly differentiate straight-line and curved portions of the diagrams. Determine the maximum shear force and bending moment in the beam.Note that answers may be positive or negative. Here, "maximum" refers to the largest magnitude value, but you should enter your shear force and bending moment with the correct sign, using the sign convention presented in Section 7.2 of the textbook. If the magnitudes of the largest positive and largest negative values are the same, enter a positive number.

Elaborate the principle of statics to calculate the internal shear force and bending moment as functions of location along an element.

Solve the problem and answer the questions that follow. - If the supports were swapped such that the left support were a roller and the right support a pin, how would your solution change? - If the value of “w” were doubled, what would be the bending moment at the left most point of the beam?

Calculate the vertical support reaction in support A. When sketching FBD, set the positive directions of both reactions in the positive direction of y axis. Enter your answer in kN to three decimal places.

Complete/calculate the following: (Where applicable, express the results as the (x, y, z) components of a Cartesian vector) 1. Draw the free-body diagram (FBD), showing the appropriate reaction forces and/or moments at the supports. (You must show the reactions in their component form i.e. show RAx, MRAX etc. on the FBD). Note: The support at point A is not able to resist a moment about the 'X' axis but is able to resist a force in this direction. 2. The unit vector ÅBc 3. The position vector Tɛ/a 4. The position vector īB/a
