1. Introduction-If power transmitted between two shafts is small, motion between them may be obtained by using two plain cylinders or discs 1 and 2 as shown in fig. -If there is no slip of one surface relative to the other, a definite motion of 1 can be transmitted to 2 and vice-versa. Such wheels are termed as “ friction wheels”. However, as the power transmitted increases, slip occurs between the discs and the motion no longer remains definite. -Assuming no slipping of the two surfaces, t

GEARTRAIN:When two or more gears are made to mesh with each other to transmit power from one shaft to another. Such a combination is called gear train or train of toothed wheels. The nature of the train used depends upon the velocity ratio required and the relative position of the axes of shafts. A gear train may consist of spur, bevel or spiral gears.

Velocity and Acceleration Analysis
Velocity and Acceleration Analysis-There are many methods for determining the velocity of any point on a link in a mechanism whose direction of motion (i.e. path) and velocity of some other point on the same link is known in magnitude and direction, yet the following two methods: 1Instantaneous centre method 2Relative velocity method -The instantaneous centre method is convenient and easy to apply in simple mechanisms, whereas the relative velocity method may be used to any configuration dia

STEAM Project
A solar system STEAM (Science, Technology, Engineering, Arts, and Mathematics) project is a hands-on learning activity that encourages students to explore and understand the solar system using a multidisciplinary approach. The project is typically designed for middle and high school students, although it can be adapted for elementary students as well. Note: this work was done by Ms. Areej Elsayary and Ms. Manar Wehbe
