Can mercury used in hydrometer? Historically, elemental mercury was used in hydrometers as a weight. The amount of mercury was small – often less than one gram, depending on the size of the instrument. Non-mercury hydrometers that use lead ballast for the weight are now used. How do you measure air pressure without a barometer? […]

What causes a vehicle to yaw? What Does Yaw Mean? Yaw happens when the weight of your vehicle shifts from its center of gravity to the left or the right.
