**Problem Statement:** Consider the beam illustrated in the figure below. You are required to draw the influence lines for \( R_a \), \( R_c \), \( R_e \), \( V_b \), and \( M_b \), and determine the following maximum responses due to: - A concentrated live load of \( "a" \) kN, - A uniformly distributed live load of \( "b" \) kN/m, - A uniformly distributed dead load of \( "c" \) kN/m. **Tasks:** a. Calculate the maximum upward reaction at point A in kN. If there is no upward reaction, indicate with "0". b. Calculate the maximum upward reaction at point C in kN. If there is no upward reaction, indicate with "0". c. Calculate the maximum upward reaction at point E in kN. If there is no upward reaction, indicate with "0". d. Determine the maximum negative shear at point B in kN. If no negative shear occurs, indicate with "0". e. Determine the maximum positive moment at point B in kN-m. If there is no positive moment, indicate with "0". **Beam Diagram Explanation:** - The beam is supported at three points: A, C, and E, with intermediate points B and D marked. - The beam extends horizontally with the following segment lengths: - \( AB = 2 \) m - \( BC = 4.5 \) m - \( CD = 2 \) m - \( DE = 3 \) m - \( EF = 1.5 \) m Support symbols indicate that points A, C, and E provide vertical reactions to loads applied to the beam. The dot at point D indicates a hinge or a point of interest but not a support. Ensure proper calculations and clear graphical representation of influence lines for precise analysis and understanding.

Influence Lines

The graphs that show the variation of a function at a specific point on a beam or truss due to a unit load placed at any point along the structure are known as influence lines in engineering. Some common functions that are studied with influence lines are shear, moment, and deflection. In designing beams and trusses, it is important to use influence lines in structures where loads would move along their span such as bridges, crane rails, conveyor belts, floor girders, etc. The influence lines help to study where a load will create the maximum effect for any of the functions.
