TL;DR Summary

Yield Strength value as well as maximum load capacity. Need equations and possibly a break down on how to solve the issue.

Summary: Yield Strength value as well as maximum load capacity. Need equations and possibly a break down on how to solve the issue.

So let's say I have a Wooden Street pole and I want to mount a steel bracket using metal bands to the street pole. The bracket will be mounted to the beam using 4 steel bolts with washers. The bracket will have a perpendicular steel beam attached. I'm looking to measure the max load capacity the bracket can withstand as well as the yield strength at various load capacities. Analyzing the stress and areas of weaknesses. The load will be various wind speeds. Please include equations on how to determine these results.

Welcome to the PF.

Does the city know that you are going to be mounting something to one of their poles? What kind of load are you wanting to support? What will be below the load in case the support fails (people?).

 

[kardai]

This is a hypothetical. Nothing will be actually mounted to city poles. The load will need to take into account the beam connected to the bracket as well as high wind speed loads.

It sure sounds more than hypothetical with exactly 4 bolts.

It is also self-contradictory. It says the bracket is mounted with bolts, and that it is mounted with bands. Which is it?

If you are expecting equations so that you can plug numbers into a formula and calculate an answer on a calculator, then your understanding of mechanical analysis is not good enough.

How about you just tell us what you are trying to accomplish and see if we can help?

If it is homework, then it should be posted on a homework forum and you need to show us your work.

Please provide a diagram showing what you think the forces/loads/reactions might be on your purposed structure; and we will then go from there.
