An investigation into car safety features

Extracts from this document...

Introduction

An investigation into car safety features

Plan

Jaguar has employed me in the technical testing department. Recent tests on the S-type sport model, performed by MIRA (The Motor Industry Research Association), indicate that forces on the driver, both internally and externally are unacceptably high. The S-type sport is fitted with the following safety features as standard:

• Seatbelts
• Airbags
• Crumple Zones
• Side impact bars

I have been asked to investigate experimentally one of these features and from my results evaluate the effectiveness of the feature. I then have to write a full and detailed report of my investigation and the findings will be presented to the Board of Directors at their next quarterly meeting.

Objectives of the investigation

1. Devise an experiment for testing safety features of cars which can be carried out in the classroom

Middle

Repeat the experiment using various velocities and different amounts of volume of air in the airbag

Problems

Solution
When the car has finished the car has finished the recorder will still be going be which could affect the results

Watch the car and have your finger on the record button ready to stop it

Make sure the car travels in a straight line otherwise it may affect the velocity or won’t hit the airbag head on. Which will affect your results

Line the car up straight so that it travels in a straight line. Make sure the wheels are straight because that could also stop it from going in a straight line

Velocity

To find the velocity form my results I need a formula:

Loss in PE = gain in KE

Mgh =  mv2

Gravity= 9.81

 Height (m) Gravity Velocity (m/s) 0.1 9.81 1.4 0.2 9.81 1.9 0.3 9.81 2.4 0.4 9.81 2.8 0.5 9.81 3.1 0.6 9.81 3.4 0.7 9.81 3.7

From the results and graphs from the experiment you can see how the use of an airbag certainly puts less force onto the driver’s body therefore there being less chance of an injury or even death. Also the airbag will increase the time the person will need to be brought to a stop and decreasing the pressure on the body again. The important thing about a car safety feature is to protect/cushion the person who is involved in the accident. My experiments have showed that the airbag is a successful safety device which has saved lives and should be introduced into all cars

The nature of the surface determines the co-efficient of friction, for instance glass has a low co-efficient of friction, while sand has a higher one.
