Wheel/axle set up report

Wheel/axle assembly report

Contents

1 . Terms of reference

This kind of report is completed as requirement of the outcome two Relationship between Linear and Angular Motion. A rotating wheel travelling along a surface has both slanted motion and linear motion. Hence it will eventually possess kinetic energy due to its linear velocity called kinetic energy of translation, and kinetic energy due to its angular velocity known as kinetic energy of rotation. The aim of this report is usually to define distinctions between tested and theoretical distance went by the tire used during an test.

2 . 2 . Method

In order to carry out test electric electric motor was attached to axle assembly and optical tachometer was used to record rpm from the axle in the same period value of V and A had been recorded by simply 2 pencil Y/T recorder. Time used by the axle assembly to travel up the ramp was recorded by simply one of the college students using a stopwatch. Stopwatch was started once axle assemblage touched the ramp and stopped once wheels travelling up the slope. Then put in place which wheel stopped was marked and measurement was taken to decide distance went by the axle assembly.
