2D diagrams are flat while 3D diagrams have depth and volume.

• 2D diagrams are represented on a flat surface while 3D diagrams have depth and volume.

• 2D diagrams are used to represent objects or structures in a two-dimensional plane while 3D diagrams are used to represent objects or structures in a three-dimensional space.

• 2D diagrams are commonly used in engineering drawings, architectural plans, and circuit diagrams...read more

The micrometre least count formula is the ratio of the pitch of the screw gauge to the number of divisions on the circular scale.

• The formula is LC = Pitch / Number of divisions on circular scale

• LC stands for least count

• Pitch is the distance moved by the spindle per revolution

• The number of divisions on the circular scale is the number of equally spaced divisions on the circular scale

• The formula is used to calculate...read more

The second law of thermodynamics states that the total entropy of a closed system always increases over time.

• Entropy of a system tends to increase over time

• Heat cannot spontaneously flow from a colder location to a hotter location

• Efficiency of a heat engine is always less than 100%

• Entropy of the universe is always increasing

A jig is a tool used to guide and control the movement of a cutting tool, while a fixture is used to hold and position a workpiece during machining.

• Jigs are used to guide the cutting tool, while fixtures hold the workpiece.

• Jigs are used in drilling, reaming, and tapping operations, while fixtures are used in milling, grinding, and turning operations.

• Jigs are often custom-made for specific operations, while fixture...read more

Mechanisms are devices that transmit or transform motion, force, or energy from one component to another.

• There are four types of mechanisms: lever, pulley, wheel and axle, and inclined plane.

• Lever mechanisms involve a rigid bar that pivots around a fixed point.

• Pulley mechanisms use a wheel and rope to transmit force.

• Wheel and axle mechanisms involve a wheel rotating around a central axis.

• Inclined plane mechanisms ...read more
