Help with some math problems:
1) The radii of sprocket assembles and wheel of bike are 4in, 2in, and 14in. The cyclist pedals 1Rev/sec, find the angular velocity of the wheel sprocket and the Linear Velocity of the bike.
2)The diamater of a hoist is 10in, and the equipment being raised is 1ft. Find the # of degrees the drum rotates.
3) There are 2 gears. The large gear spins the smaller gear. The large gear has a diamater of 30 cm and the smaller one has a diameter of 8cm. The large gear spins 4 rev/min:
How fast is the large gear/small gear in radians per minute
How fast is the small gear in revolutions per minute
What is the linear velocity of the large gear/small gear
If you double the angular velocity by using gears, what is te ratio of diameter of gears? Wich gear does the driving?
4) There are two towns. Town A= 42 degrees 7' 15" and Town B= 25degrees 45' 37"
the radius=40000miles, how many miles apart are the two towns?
5)Jupiters when closest to Earth is 390,000,000 miles from Earth, apparent size is an angle of 0 degrees 0' 46.9". Find the diameter.
