1. why is it illegal to alter the odometer on a vehicle?

2. how do you “flash” your high beams?

3. what affects the size of blind spots?

4. why is it a good idea to lock your doors while driving?

5. what are the chief advantages of power brakes over standard brakes?

critical thinking:
1. you start your car and begin to pull out of a parking space. after leaving the space, you notice that the brake light on your instrument panel is still on. what should you do?

5.a fishing rod is formed from a composite material of 0.5 kg of glass fibers embedded in a matrix of 0.5 kg of epoxy resin. the glass fibers are assumed to be long, continuous and unidirectional. to achieve a greater stiffness it is proposed to use a different composite that is comprised of long continuous carbon fibers that will be embedded in a matrix of 0.5 kg of epoxy resin. if the modulus of elasticity of the carbon fiber composite is 10% greater than the elastic modulus of the glass fiber composite, estimate the mass of carbon fibers that will be used to make the carbon fiber composite. assume the applied tensile stress is parallel to the direction of the long axis of the fibers. the epoxy resin, glass fiber, and carbon fiber have an elastic modulus of 5, 86, and 350 gpa respectively and a density of 1100, 2500, and 1800 respectively.
