The siphon shown is used to transfer liquid from a higher level to a lower level. If the fluid is drawn up and is continuous through the tube, determine the velocity of flow of gasoline if the vertical distance from the liquid surface to the outlet is 1.0 m.
 
   

   
  a.
  1.1 m/s
   
  b.
  2.2 m/s
   
  c.
  4.4 m/s
   
  d.
  9.8 m/s
   
  e.
  6.5 m/s

Question 2

The free-body diagram below represents a 1500-kg car sitting on a 3000-kg bridge supported at its far ends. The car's position is three quarters of the length L from the left end of the bridge. Identify the one error in the torque equation below:
 
   
 
 
 
   
  a.
  never produces a torque on the bridge no matter where the axis of rotation is placed.
   
  b.
  never produces a torque on the bridge no matter where the axis of rotation is placed.
   
  c.
  cannot produce a torque on the bridge no matter where the axis of rotation is taken since it is at the center of the bridge.
   
  d.
  Because the perpendicular distance to from the left end of the bridge is 0, F₁L should be 0.
   
  e.
  Because the perpendicular distance to from the right end of the bridge is 0, F₂L should be 0.
