The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object's speed in the rotating frame (more precisely, to the component of its velocity that is perpendicular to the axis of rotation).
Consider one simple example where both linear and angular motions are involved. Consider a link OB hinged at O rotating in clockwise direction with angular velocity .Consider a block sliding relative to the link with constant speed.
Sliding block experiences an acceleration whose direction is given by rotating the relative sliding velocity vector by 90 degree in the sense given by angular velocity of link. This acceleration is known as Coriolis component of acceleration
Hence Coriolis component is such that it leads the sliding velocity vector by 90 degree.
4) The sense of Coriolis component is such that it
leads the sliding velocity vector by 90 degree

Pre-tensioning reduces the maximum tensile stress in the bolts
Bolts in the flanged end of a pressure vessel are usually pre-tensioned, because Pre-tensioning reduces the maximum tensile stress in the bolts.

The Hartung Governor is spring controlled load governor categorised under the centrifugal governors. Hartung Governor is also working the same as the Hartnell governor instead of the spring load on the sleeve, spring load on the fly balls.
To raise the bow and lower the stern
The rotor of a ship rotates in clockwise direction when viewed from stern and the ship takes a left turn. The effect of gyroscopic couple acting on it will be to raise the bow and lower the stern.
