Demonstration Problem: 5.1.
This example illustrates the procedure for a relatively simple case when the threeforce member is horizontal and the two-force member is an inclined strut.
Calculate the force in member BD and reaction at the pinned connection
Demonstration Problem: 4.1.
The figure below shows a four-panel Howe bridge truss acted upon by three concentrated loads.
Calculate the internal forces in the members of the truss if forces F1 = 50.kN, F2 = 100 kN
and F3 = 150 kN. The distances x and y ar
Demonstration Problem 3.1.
The beam shown below is simply supported, meaning that it has one roller support
and one pinned support.
Given the following load configuration, calculate the two support reactions "A y"
and "B y":
Step (1) Draw the free body di
