The law of the Conservation of Energy states...

• Energy can neither be created nor destroyed
• There is no such thing as energy
• We create our own energy
• There is only kinetic energy

Choose the correct formula to Calculate Young's Modulus.

• s = ut + 1/2 at²
• σ = F/A
• a² + b² = c²
• E = stress ÷ strain

If a simply supported beam is in equilibrium, what can we say is true about its moments.
