How does physical inactivity contribute to heart disease?
How does physical inactivity contribute to heart disease? How does physical inactivity increase the risk of heart and circulatory diseases? Being inactive can lead to fatty material building up in your arteries (the blood vessels that carry blood to your organs). If the arteries that carry blood to your heart get damaged and clogged, it […]
What is the probability that two people in a group will have the same birthday in a non leap year?
What happens after ultimate tensile strength?
What happens after ultimate tensile strength? However, once the tensile strength is exceeded, the test specimen begins to thin down, or neck, at some location along the length. All of the rest of the deformation to failure occurs at this point as the stress is concentrated in this area of reduced cross section. Why does […]
How do you calculate bearings to choose?
How do you calculate bearings to choose? Bearing Rating Life Calculation C = Dynamic Capacity (dN or Lbs) P = Equivalent Bearing Load (N or Lbs) N = Rotating speed in RPM. e = 3.0 for ball bearings, 10/3 for roller bearings. What bearing type will not accept radial loads? Ball Thrust Bearing Ball thrust […]
Where is a strain gauge used?
Where is a strain gauge used? Strain gauges are used to measure the torque applied by a motor, turbine, or engine to fans, generators, wheels, or propellers. This equipment is found in power plants, ships, refineries, automobiles and industry at large. Power is obtained by measuring the strain and rotational speed on a shaft. How […]
What is the low voltage contact limit?
What is the low voltage contact limit? Section 680.2 defines the Low Voltage Contact Limit as. A voltage not exceeding the following values: (1) 15 volts (RMS) for sinusoidal ac. (2) 21.2 volts peak for nonsinusoidal ac. Is low voltage wiring required to be in conduit? Low-voltage wiring shall not be strapped to conduit. How […]
At what temperature does air become solid?
At what temperature does air become solid? Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O2, like liquid oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum. Can you make solid […]

Why did we stop using steam engines?
Why did we stop using steam engines? According to the designers, diesel engines could run faster and work longer than steam locomotives. They used a vast amount of energy to build up steam pressure, which had to be discarded whenever the locomotive stopped or shut down. In every week of operation, a locomotive consumed its […]
