How a beam resists bending. (Moment of Inertia)

Rubber Band simulation of a beam subjected to bending.

In the post “Stress, Strain and finding center“, I talked about simple compression and tension and how beam or column elongates under tension and shrinks under compression. In the elastic portion of the stress strain curve the beam is acting like a very very strong

Episode 27 – Statics Part II – Moments

A drawing of the problem to be solved

First, I want to announce the Repurpose Contest page is up. This includes pictures of the items for the April 2012 contest.

This episode is the next step in complexity from Episode 25. The problem is very similar to the last one except the force and the rope are connected at different points.

A

Episode 011: Using skills to solve problems.

John Henry told his captain Lord a man ain’t nothing but a man But before I’d let your steam drill beat me down I’d die with a hammer in my hand In this episode I will tell a story about how I used some of the skills we have already talked about and a few

Episode 9 – Making things Level.

Level is a very desirable property in many cases such as counter-tops and floors. A door swinging across a foor that is not level may very well bind and catch on the floor. Anyone who has ever used a stove-top where the burners are not level knows the frustration of all the grease and

Episode 7 – Simple Machines Part 2

This episode is a continuation of the previous episode. In this one we continue to explore the force and distance relationship with three new simple machines: the pulley, the wheel and axle, and the screw.

II also want to take this time to introduce a facebook page for this blog. The facebook page is: Create

Episode 6 – Simple Machines Part 1

In this episode we will discuss simple machines and the concept trading distance for force to get the same work completed. Work is defined in physics as Force X Distance. Often it is advantageous to use less force over a greater distance to accomplish work that could not be done otherwise. Simple machines are designed
