If M = 0.50 kg, L = 1.2 m, and the mass of each connecting rod shown is negligible, what is the rotational inertia about an axis perpendicular to the paper through the center of mass? Treat the mass as particles.
 
 
 
   
  a.
  3.7 kgm2
   
  b.
  2.8 kgm2
   
  c.
  3.2 kgm2
   
  d.
  2.3 kgm2
   
  e.
  3.9 kgm2

Question 2

A wheel (radius = 0.20 m) is mounted on a frictionless, horizontal axis. A light cord wrapped around the wheel supports a 0.50-kg object, as shown in the figure. When released from rest the object falls with a downward acceleration of 5.0 m/s2. What is the rotational inertia of the wheel?
 
 
 
   
  a.
  0.023 kgm2
   
  b.
  0.027 kgm2
   
  c.
  0.016 kgm2
   
  d.
  0.019 kgm2
   
  e.
  0.032 kgm2

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).
