SUMMARY

The discussion centers on calculating the lifting capacity of a wheelbarrow given specific parameters. Using a 2 m long wheelbarrow that weighs 80N, with its center of gravity 0.6m from the wheel, the effective lifting force can be determined through torque calculations. The torque equation, Torque = force x perpendicular distance, is essential in solving for the maximum load that can be lifted. The force enabling the lift beyond 450N originates from the mechanical advantage provided by the wheelbarrow's design.

PREREQUISITES
  • Understanding of basic physics concepts, particularly torque and force.
  • Familiarity with the principles of mechanical advantage.
  • Knowledge of how to apply the torque equation in practical scenarios.
  • Ability to perform calculations involving forces and distances.
NEXT STEPS
  • Study the principles of mechanical advantage in simple machines.
  • Learn how to apply the torque equation in various contexts.
  • Explore real-world applications of wheelbarrows and other lever systems.
  • Investigate the effects of load distribution on lifting capacity.
USEFUL FOR

Students studying physics, engineers designing lifting equipment, and anyone interested in understanding the mechanics of simple machines like wheelbarrows.

Homework Statement


suppose that you can lift no more than 450N unaided.
a) how much can you lift using a 2 m long wheel barrow? assume that the wheelbarrow weighs 80N and that its center of gravity is .6m from the wheel. in addition, assume hat the load carried in the wheelbarrow is also .6m from the wheel
b) where does the force come from to enable you to lift more than 450N when you use the wheelbarrow?


Homework Equations


Torque = force x perpendicular distance between the axis and the line of action of the force
sum of torques = Ia


The Attempt at a Solution


I thought I could set the weight lifted equal to forces with the angled lift, but either that's wrong or i don't know how to do it.

Think of force * distance for the weight and your lift, both measured from the wheel
