Technologies include: • Seatbelts • Airbags • Crumple zones • Traction control All these technologies are in place to help reduce the effects of a collision. Seatbelts are one of the most affective safety implications in place. They first of all stop a person during a collision from dismounting from the seat of the vehicle. How the seatbelt works is a bit of physics‚ inside the locking mechanism is a weight connected to the roll of belt‚ during

Chapter 13 – States of Matter Pressure (P) – the amount of force per unit area. Pressure=F/a or P=F/a Pascal’s Principle “Any change in pressure at a point on a confined fluid is transmitted throughout the fluid”. Any change is transmitted throughout the fluid. Buoyancy & Archimedes Principle “When an object is submerged in a fluid‚ it displaces a certain volume of that fluid. The amount of force pushing upward on the object is equal to the density of the fluid (Ï) times the acceleration

Calculations- 1. Main Show Tank Calculation: The main show tanks radius is 70 feet. Based on that the tank is a sphere-shaped and we have to find the volume‚ I used the formula for the sphere volume which is: V= 4/3(3.14 x r^3) V= 4/3(3.14 x 70^3) V= 4/3(1‚077‚020) V= 1‚436‚026.66666... V= 1‚436‚027 But I have to find the volume of the quarter sphere-shaped‚ so: V= 1/4 x 1‚436‚027 V= 359‚007 The volume of the quarter-shaped tank is 359‚007 cubic feet Holding Tank Calculations- 2.

Could you imagine a world without accidents with cars‚ that involved seatbelts? This is possible! Car manufactures should create a system that prevents vehicles from operating when the seatbelt is disengaged. We would be able to have less deaths and injuries from people that don’t normally wear their seatbelts. As well as a great deal of money saved from insurance and accident-related payments. Even better‚ there will be an increase to the amount of safety you are given when people use these automobiles

Energy: the ability to do work. Work= force x displacement. Power=energy/time Power is measured in watts or horsepower. Joules/sec=watts 1hp=746w=1kw Basal metabolic rate 2000kcal/day= 100w Batteries store energy in chemical form. They release energy by pumping electrons’ through wires from the minus pole to the plus pole.
