Heavy Duty Trolley Plastic Bending & Strain Energy

Click For Summary
SUMMARY

The discussion centers on solving a physics problem related to bending and strain energy in a heavy-duty trolley. The user struggles particularly with Part (b) of the problem and seeks clarification on the derivation of the tension (T) expression, which is defined as T = P*L2 = P*R*(1-cosθ). The user has made an attempt at Part (a) but is unsure about the accuracy of their calculations and requests feedback on their approach. The key equations involved are M = P*L1 = P*R*sinθ and T = P*L2 = P*R*(1-cosθ).

PREREQUISITES
  • Understanding of basic physics concepts, particularly mechanics.
  • Familiarity with trigonometric functions and their applications in physics.
  • Knowledge of bending moments and strain energy principles.
  • Ability to interpret and manipulate equations related to forces and moments.
NEXT STEPS
  • Study the derivation of tension in mechanical systems, focusing on T = P*R*(1-cosθ).
  • Explore the principles of bending moments in static equilibrium.
  • Review trigonometric identities and their applications in physics problems.
  • Investigate strain energy calculations in materials under load.
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators seeking to clarify concepts related to bending and strain energy in practical applications.

The link above have the full problem
I mostly have issue with Part (b) of the problem where am not familiar with and don't know how to solve that part. I was wondering if someone can put some light in the tunnel or provide a link where I can study about this type of problems

As for Part (a) I attempted it and although came really close to the solution is not what am asked to prove so I was wondering if someone can spot any problem with my calculation there

Homework Equations



M = P*L1 = P*R*sinθ
T = P*L2 = P*R*(1-cosθ)

The Attempt at a Solution



This is my attemp and what method I used for it

Show me how you derived the expression for T .

I am not sure I understood correctly what you are looking for but I included both what T is = to and its derived version
