Hello, we're writing a physics exam tomorrow. I've been given an exercise sheet. Can someone please tell me the answer? 1. A spring is stretched by exactly 0.5 m due to a tensile force of 30 N. Determine the spring stiffness. 2. What is the force on a spring (D=60N/m) that is extended by 2m?…
I wanted to ask about the unit for mechanical stress. I know it's N/m^2. But I often read that the unit is Pa or GPa? But is both really possible? Pa and GPa?
Hello, I need help with this task. (For a) I have delta l=root(l0^2-d^2)-delta x-l0 and for b) F=-k*(root(l0^2-d^2)-delta x-l0)) Because in c) below values for l0, d and k are given, but wouldn’t one just need the value of k, since 1/k(eff)=1/k1+1/k2. If I'm wrong, I'd appreciate a detailed solution. Thank you in advance for…
For example, which body is a Hookean body with high elasticity and low Young's modulus? PS Rubber is not a Hookeian body!
I've done tasks a) and b), but I don't understand task c). Why does spring stiffness depend on the length?
Hi, I wanted to study for my exam tomorrow and needed the answers to this worksheet to compare my answers. If anyone would like to help me solve this worksheet, it would be really nice.
