Sat, 22 Apr 2017 01:27:49 +0000Now, let’s apply Equation (1) to an example in which a blower must deliver a specific air flow to a building’s ventilating system.
Sat, 08 Apr 2017 10:57:52 +0000Soon after the first pulleys were used with belts to transmit mechanical power, engineers such as Leonhard Euler and Johann Albert Eytelwein discovered that the diameter of the pulleys used determined the speed at which they rotated. This allowed for a greater diversity in mechanical applications. We’ll set up an examination of this phenomenon today. […]
Fri, 31 Mar 2017 18:56:34 +0000Our example of a basic mechanical power transmission system consists of two pulleys connected by a drive belt.
Mon, 20 Mar 2017 14:20:10 +0000Today we’ll introduce his contemporary and partner in science, Johann Albert Eytelwein, a German mathematician and visionary, a true engineering trailblazer...
Thu, 09 Mar 2017 22:33:02 +0000Euler authored his first theoretical essays on the science and mathematics of pulleys after experimenting with combining them with belts in order to transmit mechanical power.
Tue, 28 Feb 2017 14:28:55 +0000Today we’ll calculate just how much friction is present within the example compound pulley we’ve been working with.
Wed, 15 Feb 2017 16:04:23 +0000Today we’ll get two steps closer to demonstrating this reality as we work a compound pulley’s numerical puzzle, shuffling equations like a Rubik’s Cube ...
Mon, 06 Feb 2017 19:22:12 +0000Today we'll begin to numerically demonstrate their inequality by first solving for work output, and later work input.
Sat, 28 Jan 2017 21:16:06 +0000The tribometre shown in his sketch here is one of history's earliest recorded attempts to understand the phenomenon of friction.
Mon, 16 Jan 2017 19:45:33 +0000In other words, work input is not equal to work output in a real world situation in which pulley wheels present a source of friction.
