Situation 27: Given: S = 4.3 m, θ = 45⁰
1. Which of the following gives the maximum ordinate of the influence line for the force in member JK?
A. -1.0 C. -0.5
B. 1.0 D. 0.5
2. Calculate the maximum force (kN) in member JK due to a moving highway truck load as follows:
W1 = 19.6 kN
W2 = 78.4 kN
Distance between loads = 4.3 m
A. 88.20 (T) C. 73.46 (T)
B. 88.20 (C) D. 73.46 (C)
3. Determine the maximum force (kN) in member JK due to moving highway lane load as follows:
Uniformly distributed load = 9.35 kN/m
Concentrated load = 116 kN
A. 196.4 (T) C. 181.48 (C)
B. 196.4 (C) D. 181.48 (T)

Solid talaga mga vedios mo Sir👌. Thank you
Salamat sa panonood idol! Pashare nalang din sa iba. Hehe salamat!
Thank you very much, Engr/Sir Harf! Very helpful to self-reviewees like me..
Please find time to create a video about Absolut Volume method of calculating materials in concrete.
More power, Sir! 😊
Salamat po sa suggestion!
Thank you sir. Big help po
Thank you sir harf
Bilib na talaga ako sayo boss.
Sir question lang po,
Bale if, nassume ko na compression yung member JK postive ang mga answers pero yung magiging drawing ko ng shear diagram is downward, and sa final answer is consider compression as negative? Thanks po

Ang influence line diagram po dito ay hindi shear diagram kundi axial force diagram nung member Jk. Sa influence line, by default tama na nasa ilalim ang compression at sa ibabaw ang tension. So kung inassume mo na compression, positive ang lalabas pero nasa ilalim padin po siya ng diagram. Hope this helps!
Thank you po sir, great help po sa mga nagrereview for board exam mga videos niyo. God bless you po ❤️
