Question
1. The axle loads for the truck shown below are P1 = 8 kips, P2 = 6 kips, and P3 = 4 kips. Calculate the maximum moment (M) and maximum shear (V) as the truck is driven across the bridge.
   
   Remember this will require the loads being evaluated at two different locations.

### Diagram Explanation:

- The diagram shows a side view of a truck positioned on a bridge.
- The bridge is represented as a straight horizontal line between two points labeled A and B.
- The truck is depicted with three axles, each with forces acting downwards:
  - P1 (8 kips) is located at the front axle.
  - P2 (6 kips) is situated at the middle axle.
  - P3 (4 kips) is at the rear axle.
- The positions of the axles are marked by arrows pointing downwards from the axles to the bridge.
- Spacing measurements are provided below the bridge:
  - The distance from A to the front axle (P1) is 20 feet.
  - The distance between the front axle (P1) and the middle axle (P2) is 8 feet.
  - The total span of the bridge from A to B is 60 feet.

This setup indicates that to find the maximum moment and shear, calculations must be done as the truck moves along the bridge, considering positions of axle loads relative to the supports.
