Hi all,
First to clarify: this is no homework question. I am working on a construction and am really puzzled about the following problem.
I need a spring to hold an object in place during sideway shocks.
I am really puzzled about the fact if friction helps one or two times. In other words: do I count friction only between the block and the floor, or also between the pushing part of the spring and the block (meaning that friction counts two times and they both "help" in keeping the block in its place).
This would mean that:
Frictionforce-spring_block = staticfriction_coeff(spring-block) * (pretension_force + weight)
Frictionforce-block_floor = staticfriction_coeff(block-floor) * (pretension_force + weight)
