GagsDev Update


I decided to program something new, and something involving servers. I ended up designing a simple console framework made for text-based programs and games. To make it more interesting, I left in the full capability of HTML in the output window. This means that instead of plain text, individual lines can be colored, styled, hyperlinked, etc. Additionally, images and other multimedia content can be embedded, making this platform a hybrid of classic text-based programs with the full graphical capabilities of HTML5.

On my website, I have posted two demos so far, with more to come soon!

One Big Rotation Problem - Part 1


This problem is part of a larger rotation problem I made up to help my friends study physics.

A solid metal wheel with a radius of 3.0 cm and a mass of 2.0 kg is released from rest from the top of a frictionless ramp, 4.0 m from the ground.  It takes 3.0 sec to roll to the bottom of the ramp without slipping. Determine (a) The wheel’s moment of inertia, (b) the final linear velocity, (c) the final angular velocity, (d) the linear acceleration of the wheel, (e) the angular acceleration of the wheel (f) the number of revolutions the wheel turns through, (g) the net torque on the wheel, (h) the distance along the ramp that the wheel travels, and (i) the angle of incline of the ramp in degrees.

A complete walkthrough of the problem can be seen in the full post.
