Find Stress of the Rectangular Block

Click For Summary
SUMMARY

The discussion focuses on calculating the dimensions of a rectangular block subjected to a vertical force of 2000 N while ensuring that the stress remains below 210 MPa. The material's modulus of elasticity is given as 193 x 10^3 MPa. The block is fixed at both ends, which influences the stress distribution. The primary goal is to determine the appropriate dimensions of the block to maintain stress within the specified limit.

PREREQUISITES
  • Understanding of stress and strain concepts in materials science
  • Knowledge of axial and transverse loading conditions
  • Familiarity with the modulus of elasticity and its implications on material behavior
  • Basic principles of mechanics of materials, including beam theory
NEXT STEPS
  • Calculate the dimensions of the rectangular block using the formula for stress: σ = F/A
  • Explore the effects of fixed supports on stress distribution in beams
  • Investigate the relationship between force, area, and stress in different loading scenarios
  • Learn about safety factors in engineering design to ensure structural integrity
USEFUL FOR

Engineering students, mechanical engineers, and anyone involved in structural design and analysis of materials under load.

For this question, I need to find the force that will be acting on a rectangular block.

E = 193 x 10^3 MPa
Max. Stress = 210 MPa
F= 2000N

The rectangular block is fixed at both ends (bolted on to another metal object)

I need to find the dimensions for this block. L, length can be as long as 30mm

How do I find the dimensions of the block that will keep the stressunder 210MPa.

I only need the stress that will be there due to the vertical force downwards on the rectangular block.

Help pleaseeeeeeeeee

Is this a school assignment? Is the 2000 N force applied axially to the rectangular block? Or is the 2000 N force a point load applied transversely to the rectangular block midspan?
