(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A trailer carrying a boat is supported by a scale which initially reads 48kg. The boat is moved 0.15m further back on the trailer. The scale now reads 37kg. What is the mass of the boat?

2. Relevant equations

torque = F(perpendicular) * d

For equilibrium:

Sum moments = 0

Sum Fy=0

Sum Fx=0

3. The attempt at a solution

Taking moments about the wheel:

(48*9.81*6)+9.81*m*x=0

(37*9.81*6)+(9.81*m*(x-0.15))=0

Two equations and two unknowns (m and x). Solve.
