Homework Help Overview

The discussion revolves around determining the coefficients of friction for a wooden block and the spring constant 'k' for springs in a specific setup involving a board. Participants are exploring the relationships between these physical properties and their calculations.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to ascertain the approximate values for kinetic and static friction, as well as the spring constant for springs attached to a board. Questions are raised about whether to double the spring constant when springs are in parallel.

Discussion Status

Some participants are questioning the appropriateness of specific values for the coefficient of friction and discussing how to combine spring constants when springs are arranged in parallel. There is an ongoing exploration of the necessary equations and methods for calculating these values.

Contextual Notes

There is a mention of attachments that may contain relevant images or diagrams, which could influence the understanding of the problem. Additionally, one participant notes a delay in image approval, which may affect the discussion's progression.

Coefficient of Friction and Spring constant

What would the approximate value of (kinetic, and if possible, static) friction be for a block of wood of this nature:
\\Attachment 1 and 2

And how about the 'k' value for these springs? How would i go about calculating this sort of problem when the two springs are attached to a board which is the place of impact? Would i double the value of k?

Awaiting for the image to be approved Dekoi. "Dekoi" is of French origin I pressumed.
 
Does a value of 0.6 sound correct for the coefficient of friction between a steel ball and a wooden-ramp shown above?

2 springs in parallel: add the k values to find the total k value.

Not sure what you're doing here. Do you need equations to determine spring constant from spring dimensions?
