To determine the maximum axial force for a 6.0m long steel member with a diameter of 50mm, the axial stress must not exceed 175MPa and elongation must be limited to 0.14% of its length. The area of the cross-section can be calculated using the formula for the area of a circle, which is necessary for applying the stress formula. The relationship between stress and force indicates that multiplying the allowable stress by the area yields the maximum force. Additionally, understanding the material properties of steel, including its elongation per unit stress, is crucial for ensuring the elongation limit is not surpassed. The calculated maximum axial force is confirmed to be 343.5 kN.

Hey guys, I need setting up this problem. Here it is:
A structural member is fabricated from a solid round bar of steel with a diameter D=50mm. If the member is 6.0m long, determine the maximum axial force that can be applied if the axial stress is not to exceed 175MPa and the total elongation is not to exceed 0.14& of its length.

I know the answer is 343.5 KN but i am unsure of how to get it. Thanks
 
Physics news on Phys.org
Stress or Pressure [Pa] is Force per Area [N/m^2]
Did you try multiplying the stress by the Area?

Do you know how much the steel stretches per Pa?
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
