SUMMARY

The discussion centers on calculating the force required by two individuals to lift a total of 10 bags of soil, each weighing 185 N, placed on a 2.40-meter long sheet of wood. The total weight to be lifted is 1850 N, derived from multiplying the number of bags by their individual weight. The participants suggest using the concept of moments, where the weight times the distance from a chosen pivot point must equal the force times the length of the board. This approach leads to determining the individual forces exerted by each person lifting the sheet.

PREREQUISITES
  • Understanding of basic physics concepts, specifically moments and torque.
  • Familiarity with force calculations and equilibrium principles.
  • Knowledge of how to apply the lever principle in practical scenarios.
  • Ability to interpret and analyze static equilibrium problems.
NEXT STEPS
  • Study the principles of static equilibrium in physics.
  • Learn about calculating moments and torque in various contexts.
  • Explore practical applications of the lever principle in engineering.
  • Investigate real-world scenarios involving distributed loads and lifting forces.
USEFUL FOR

This discussion is beneficial for physics students, engineering students, and anyone interested in understanding the mechanics of lifting and equilibrium in practical applications.

Homework Statement



Ten bags of top soil, each weighing 185 N, are placed on a 2.40-m long sheet of wood. They are stacked 0.50 m from one end of the sheet of wood, as shown below. Two people lift the sheet of wood, one at each end. Ignore the weight of the wood, how much force must each person exert?

Homework Equations



none

10*185=1850N so that would be the total being liften since the wood is ignored
From there I am stuck as to do what http://img120.imageshack.us/img120/6727/p827rs8.th.gif

Treat it as a moment arm about one end or the other. Your choice.

The weight times the distance away from where you choose and the force times the length of the board must match shouldn't they? Since you know the total weight then you know the sum of the lifting forces must equal that.
