Users calculate the tonnage required to punch holes in a specific base metal. The formula to be used is provided along with the tensile strength for various metals. A calculator is required.
Calculating Blank Size for Rolled Sheet Metal (Screencast)
In this interactive object, students read how to calculate the blank size for cylinders in a three-roll pinch roller. A calculator is required for the brief quiz that completes the activity.
In this interactive object, part 3 in a series, learners follow the steps of the “mathemagician” to examine four numerical curiosities: What’s Special About 1089, Perfect Squares: 1089 and 9801, The Mathematical Significance of 1776, and The Calculator Number Game. The learner will also study six number patterns and look at one remarkable table. Immediate feedback is provided.
Statics - Trig: Pythagorean Theorem Calculations Using a Casio fx-260
