<span>There are two
types of modern wind turbines. In a Verical-axis wind turbines (VAWTs), the
shaft is mounted on a vertical axis perpendicular to the ground. They are
aligned with the wind so there’s no adjustment necessary when the wind
direction changes. It can’t start moving on itself that is why it needs a boost
from its electrical system to get started. It uses wires for support so the
rotor elevation is lower. They are less efficient than HAWTs due to its lower
elevation. Lower elevation means slower wind due to ground interferences. The other
type is Horizontal-axis wind turbines (HAWTs), the shaft s mounted horizontally
parallel to the ground. It is constantly aligned with the wind using a
yaw-adjustment mechanism. This mechanism moves the entire rotor left or right
in small increments. It uses a tower to lift the turbine components to an
optimum elevation for wind speed and take up very little ground space. It is
much more efficient than VAWT. </span>
When an impulse reaches the muscle fibres of a motor unit, it stimulates a reaction in each sarcomere between the actin and myosin filaments. This reaction results in the start of a contraction and the sliding filament theory.
Depends on your build, Small frame build should be between 114-127 lbs, Medium should be 127-138 lbs, and large should be 138-151 lbs. Hope this helped :)
