SUMMARY

The maximum load that a 1.5 m copper wire with a radius of 1.1 mm can suspend without breaking is determined by its elastic limit of 3 × 108 Pa and tensile strength of 4.2 × 108 Pa. The calculation involves using the formula F/A < Elastic Limit, where F is the force and A is the cross-sectional area of the wire. The area is calculated as A = πr2, leading to a maximum load of approximately 116,248.54 N. This result indicates a significant load capacity, but the calculation method should be verified for accuracy.

PREREQUISITES
  • Understanding of tensile strength and elastic limit in materials science
  • Knowledge of basic physics principles, including force and area calculations
  • Familiarity with the properties of copper as a material
  • Ability to perform calculations involving cross-sectional area (A = πr2)
NEXT STEPS
  • Research the mechanical properties of copper, including its tensile strength and elastic limit
  • Learn about the calculations involved in determining the load capacity of materials
  • Explore the effects of wire length and diameter on load-bearing capacity
  • Investigate safety factors in engineering design for load-bearing applications
USEFUL FOR

Engineers, materials scientists, and students studying mechanics or materials engineering will benefit from this discussion, particularly those interested in load calculations and material properties.

What is the maximum load that could be suspended from a copper wire of length 1.5 m and radius 1.1 mm without breaking the wire? Copper has an elastic limit of 3 × 108 Pa and a tensile strength of 4.2 × 10^8 Pa

F/A<Elastic Limit

= m(9.81) / 3.8013 = 3x10^8Pa
9.81m= 114 098 123
m= 116 248 535 N ?

Seems like an aweful lot of load, what did i do wrong on this one?
 
Physics news on Phys.org
any ideas? I worked it out one more time with the same result...
