Lab 3 : Techniques in Microscopy Title : Preparation of light microscope observe cell organisms. Objective : To observe and investigate the cell structure under the light microscope. Introduction A microscope is an instrument used to magnify and resolve a specimen. It is important to know several important features of microscopy which involves magnification‚ resolution and contrast. Magnification is the enlargement of a specimen while resolution is the ability to distinguish detail or the

simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus
