Having minor homework questions or simply want to make sure your homework answers are correct? Then use our free service to get quick answers to your homework questions in mathematics, physics, programming, economics, chemistry and biology. We already have a database of multiple homework questions and answers you can look through . If you can’t find the solutions to your homework problems, then post your homework questions and find a well-formulated answer from a professional within a very short timeframe.
Please save your time and DO NOT send us your full assignments or not precise, well stated questions in mathematics, physics, programming, economics, chemistry or biology as they will be ignored. In this section we can answer only your short questions of qualitative, primary theoretical nature (for FREE!). Use filters to display the questions to a particular subject or section. By entering your e-mail in the box "Search" you can browse the questions posted exclusively by you. Do not worry if you cannot find your question in the list after it has been submitted; every question is being checked by a moderator and appears in the list only after its approval.

• The car will be travelling around a bend of fixed radius: (50m / 100m / 200m / 500m)
• Car mass is 620kg.
• Centre of gravity is 2/3 rds of the way back horizontally between the wheels, and 1/3 rd of the height vertically up from the ground.
• Maximum width of car = 1.8 m (as defined by F1 regulations)
• Maximum height = 0.95 m
Coefficient of friction between the tyres and the road:
• Intermediate tyres in the dry: 0.7
• Intermediate tyres in the wet: 0.4
• Slicks in the dry: 0.9
• Slicks in the wet: 0.1
Calculate the new maximum speed for each bend radius, for each of the four tyre conditions.
What do they depend on? Give example use of the equations.

b) Will a saucer?
c) Will a football?
a) Why is it rounded and not pointed at the front
b) why is it thicker in the middle
c) Why is it tapered at the rear
d) Why is it flatter underneath, with a camber making it curve on top?
