**Influence Line:**The influence line is for \( V_{40^-} \) = shear just left of 40'. A load of 0.6 kip/ft is placed from 10' to 30'. A load of 0.2 kips/ft is placed from 30' to 40'. Determine \( V_{40^-} \) in kips to two decimal places. Use the correct sign.**Diagram Explanation:**The diagram is a graphical representation of an influence line for shear, specifically at a point just to the left of 40 feet along a beam. The influence line consists of straight segments forming a trapezoidal shape with the following key points:- Starts at -1 at the origin (0 feet).- Increases linearly to reach 0.5 at 20 feet.- Drops linearly back to 0 at 40 feet.- Each segment of the line is straight and represents linear relationships between the shear force and the position of the moving loads along the beam.
