In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.
A wheelbarrow is modelled as a uniform rod AB AB\,AB of length 1.5 m and mass 8 kg, with the wheel at A A\,A and the handles at BBB.
A load of mass 30 kg is placed on the barrow at the point CCC, where AC=0.5AC = 0.5AC=0.5 m. The load is modelled as a particle.
The barrow is held at rest with AB AB\,AB horizontal by a vertical force applied at BBB.
Find the magnitude of the force applied at BBB.
Find the magnitude of the vertical force exerted by the ground on the wheel at AAA.
