Question

In the wheelbarrow, the load has a perpendicular lever arm of 7.50 cm, while the hands have a perpendicular lever arm of 1.02 m. (a) What upward force must you exert to support the wheelbarrow and its load if their combined mass is 45.0 kg? (b) What force does the wheelbarrow exert on the ground?

Step 1

Given: Mass of wheelbarrow and load (m) = 45.0 kg Perpendicular lever arm of load (L\_I) = 7.50 cm = 0.075 m Perpendicular lever arm of hands (L\_not) = 1.02 m Acceleration due to gravity (g) = 9.8 m/s^2 Use the formula: F\_I = F\_not * L\_not / L\_I Substitute Show more…
