Truss Analysis

Truss Analysis

Compare the internal forces on each member of the calculated truss with the values you measured from the bar and tube measurements.

a$.$ Will the truss members support an $11$ pound load? Fill out the table.

b$.$ Calculate the Safety Factor for each member. Place answers in the table.

Force calculated is from page previous $2$ slides $-$ Calculations.

Force measured Actual force from slide $1$ last column of $2$nd data table

To calculate the safety factor in a structural member, use the formula:

$SF=\frac{S}{F}$

$SF=$ safety factor

$S=$ maximum strength a structural member can withstand before failing $($from measurements$)$

$F=$ maximum internal force calculated when a load of $11$ lbs is applied to your bridge $($from calculations$)$
