of a motor vehicle that is often not fully appreciated. The function of the steering system is to steer the front wheels in response to driver command inputs in order to provide overall directional control of the vehicle. However‚ the actual steer angles achieved are modified by the geometry of the suspension system‚ the geometry and reactions within the steering system. Steering system can be front wheel controlled‚ rear wheel control‚ all wheel control. Here we will keep

INTRODUCTION Steering wheel Torque vs. Angle Characteristics Two parameters are used to characterise this plot as shown in Figure 1. These are the steering wheel torque at 0 degree and steering torque gradient at 0 degree‚ commonly referred to as “steering stiffness” which shows whether the

This experiment seeks to demonstrate the law of reflection - the angle of incidence is equal to the angle of reflection when measured from the normal. Equipment Single slit raybox with power supply Paper Ruler Protractor Sharp Pencil Plane mirror Support for mirror (e.g. wooden block with a groove in‚ or plasticine) Method Draw a line on the paper. Place the mirror on the line and support it so it does not move. Shine the beam from the raybox towards the mirror. Use the pencil

Introduction • Snell’s Law is a formula used to describe the relationship between the angles of incidence and refraction‚ when referring to light or other waves passing through boundary between two different isotropic media‚ such as water and glass. • It’s also commonly known as ’’The Law Of Refraction’’ What is light : How is light propagated through different optic medium? • Light is the natural agent that stimulates sight and makes things visible; electromagnetic radiation from about

being used in this particular experiment is symmetrical and is taking place in a wind tunnel with a speed of 18.5m/s‚ therefore the flow is assumed to be incompressible. The different pressures along the surface of the aerofoil will be measured at an angle of attack of 4.1 degrees and 6.2 degrees. These values of pressure will then be analysed and graphs and calculations will be produced‚ the lift being calculated using the trapezium method in excel and these values and graphs will then be compared to

Question: The effect that the angle of incidence of white light has on the angle of refraction from one transparent medium to another. Introduction: Snell’s law state: When light passes from one transparent medium to another the rays of light refract (bend). Snell’s law (Law of Refraction) states that: n*=sinⅈsinr=n2n1=V1V2 for the purpose of this experiment we will be proving that: sinⅈsinr=n2n1 or n1sinⅈ=n2sinr where n1 and i are the index of refraction and angle with the normal to the surface

The lenses are see through but there is something called a critical where the angle of refraction is greater angle of incidence 90°.

Bump Steer Gauge How Much Bump Steer? Diagram A. Bump Steer Definition Bump steer is when you wheels steer themselves without input from the steering wheel. The undesirable steering is caused by bumps in the track interacting with improper length or angle of your suspension and steering linkages. Most car builders design their cars so that the effects of bump steer are minimal. However‚ you must still take care to bolt on your suspension carefully so as not to create unwanted bump steer. Make sure that

If it is assumed that V and ωr are known‚ then calculation of the induced velocity w is desired to find α i ‚ and consequently the section angle of attack α . Knowing α ‚ and the section type‚ C l and C d can be calculated‚ then the differential lift and drag of the section will follow. However‚ w depends
