1
Q
what is true when an internal pin is introduced to a system
A
- another equation of equilibrium is found
- moments around pin = 0
2
Q
what is true about the forces either left or right to an internal pin
A
- they must equate to zero
3
Q
what is the equation for the factor of safety against overturning
A
- restoring momentum/overturning moment
4
Q
what is the equation for the factor of safety against sliding
A
- total reactive forces resisting sliding/total forces tending to cause sliding
5
Q
what is the Principle of Superposition
A
if a structure is made of linear elastic material and is loaded by combination of loads which do not strain the structure beyond the linear elastic range , then the resultant effect of the total load system on the structure is equivalent to the algebraic sum of the effect of each load acting seperately
