MEMO To: Dylan Smith From: Cindy Nguyen Section: 907 Date: 10/10/16 Re: Lab 5 Belts Purpose: The primary objective of this lab is to understand the working of belts through simple experiments. Procedure: Students are given belts and research the meaning of various belt nomenclatures presented with specifications and applications. With assembled pulleys and belts on a trainer students observed the RPM from each pulley and calculated actual/theoretical speed and speed ratios using the measured diameter of the pulleys. The final part of the lab was using the Browning Catalog to find a belt drive that satisfied the requirements given. Results: The results for the labs are enclosed in the attached forms. Conclusions/Recommendations: Belts are used for mechanical power transmission with pulleys known as sheaves and also transmit motion and torque from one drive to another. Since there are a variety of belts for different uses, this allows users to specify the belt needed based on different factors required. During this lab, students learned to identify different specifications behind various belt nomenclatures and see first hand the relationship between the diameter of a sheave and the affect it has on speed ratios. Real World Applications: Belt systems are most commonly used in automobiles. They coordinate the rotational motion of the crankshaft with the camshaft and are the pacemakers of an engine. This requires high
