THREAD CUTTING - Practice Mode
1) Which material is suitable for button die chaser?
Explanation:
A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass, energy and electric charge.
On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force, weight, acceleration and velocity.
2) Which is the angle of inclination in the thread to the imaginary perpendicular line?
Explanation:
A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass, energy and electric charge.
On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force, weight, acceleration and velocity.
3) Which method is non metallic threads are produced?
Explanation:
The rate of change of displacement of a body is called Velocity.
Velocity The rate of change of position of a particle in a given direction is called its velocity. Thus velocity is displacement made by the body per unit time. Velocity is a vector quantity.
Speed The rate of change of position of particle irrespective of direction is called speed. It is measured by distance covered per unit time. Speed is a scalar quantity.
