Answer :
The question pertains to calculating the deflection and rotation of a steel beam under certain loads using moment-area theorems. Specific details on how to apply these theorems are not provided, but they would involve integrating moments and using material properties like Young's modulus.
The student's question is related to the moment-area theorems which are used to determine the deflection and rotation of points in a beam in structural engineering. This problem requires calculating stresses and deformations in a beam subjected to a combination of uniform and concentrated loads, utilizing equations derived from material properties like Young's modulus. To solve this problem using moment-area theorems, one would first calculate the moment due to the loads and then use the theorems to find the deflections at specific points of the beam.
However, the provided information does not specify the exact nature of the calculation or the final quantity required. Using moments to determine stress and deflection usually involves integrating the bending moment equation along the length of the beam, considering conditions like support reactions and point of contra flexure. The details of calculation steps can vary based on the beam's boundary conditions and load distribution.
