What happens to a beam when an external load is applied?
Think about what happens with weight on a ruler.
If you double the applied load on a beam, what happens to deflection?
Double the force, double the effect.
What is the primary factor that increases beam deflection?
If you increase weight on a beam, what would happen to its bending?
True or False: A higher moment of inertia results in greater deflection.
Think about how a thick beam resists bending compared to a thin one.
A beam of length 8 m has a uniform load of 15 kN/m. Calculate the deflection at the free end considering E = 120 GPa and I = 120 x 10^6 mm^4.
Start by ensuring all units are consistent before plugging numbers into the formula.
For a cantilever beam of 4 m length subjected to a point load of 20 kN at the free end, find the deflection using E=200 GPa and I=200 x 10^6 mm^4.
Identify the correct formula for a cantilever setup before substitution.
