Homework Statement If you change the diameter of a spring does it affect the spring constant? Assume the spring length, if fully extended, was kept constant. Homework Equations F=kx; F=mg The Attempt at a Solution From my research the spring constant (k) is measured by applying a mass and...

Thanks for your help! I may ask for more of it when I get to the electronics section…I see that is your area of expertise!

The distance to the hinges does not change, that is, if the distance is to the axis of the hinges. So I guess if that is the same then the force would be equal along any point on a vertical line.

Thanks for your quick response! I think I understand what the question is asking now from your guidance. The equation for torque is definitely helpful in seeing the relationship between force and distance and how it all affects torque. I see now for my question that applying a small force at...

Homework Statement Hi everyone! Here is the question: Can you open a heavy door more easily if you push at the handle or halfway between the handle and the hinges? Why? Homework Equations There may be some equations but I'm more interested in a general 'word' explanation. The Attempt at a...
