Question

Just answer 4 and 5. Thank you

  1. Maximum Reaction at support A, VA
  2. Maximum Reaction at support B,  VB
  3. Maximum Shear at cutting plane 1-1,  V1-1
  4. Maximum Positive and Negative Moments at cutting plane 1-1, M1-1
  5. Maximum Shear at cutting plane 2-2, V2-2

What about if the loading is 10-feet long uniform live load of 640lb/ft? Compute the same functions. 

 

Influence line for VA Influence line for VB Influence line for shearing force at section 1-1 Influence line for shearing force at section 2-2 10 ft Influence line for bending moment at section 1-1 7.33 33 /0.33 0.33 + 0.1 1.0 + 0.0 8 ft /0.0 /0.0 Movement of the load 0.73 1 70.27 5.87 22 ft B /0.0 8 ft 1.0 + 0.0 10 ft /0.0 2 1.0 /0.33 1.33 0.33 2.67 1.0 32,000 lb/axle -14 8,000 ib/axle FIGURE 1 H20 TRUCK Given the truck loading above, draw the position of the truck wheel axles to produce the maximum values of each of the functions with Influence Lines. Also, solve for these maximum values. (Consider both negative and positive values for moments)
