Engineering at Cambridge: ENGAA

Natural Sciences at Cambridge: NSAA

Assessment date: 4th November 2020

Week 1 – Mechanics

Week 2 – Electricity

Week 3 – Area/volume of shapes

Week 7 – General maths (logs, binomial, trig).

Mechanics Facts (unlike A-level, you need to remember these)A moment is the force multiplied by the distance perpendicular from the line of action of the force to the pivot. Measured in 𝑁𝑚.

Moment=Fd

∑clockwise moment=∑anticlockwisemoment

Force not perpendicular?

Turns out that L is the shortest distance along line of force to the axis. So it turns out that:l=r sin θ

Moment of acouple=Fs

Motion: v= ΔsΔ t

a= ΔvΔt

suvat equations: v=u+at s=( u+v2 )t v2=u2+2as s=ut+ 12a t 2

Newton’s second law: ∑F=Δ(mv)Δ t

F=ma F Δ t=Δ(mv)

Momentum: Δ p=m Δv momentumbefore=momentumafter

Energy: W=Fscosθ Δ E p=mg Δh Ek=12mv2

Springs: F=k Δ L Ep=12F ΔL Ep=1

2k Δ L2

Springs in series: 1keq

= 1k 1

+ 1k2

Springs in parallel: k eq=k1+k2

Density: ρ=mV Density of an alloy: ρ=ρ1V1 + ρ2V2

V 1+V 2

Young Modulus= StressStrain
