Question

How many types of motion?
What is solar eclipse?

Answer 1

Ans 1. There are basic four types of motion :
1. Rotary
2. oscillating
3. linear
4. reciprocating



Ans 2. A solar eclipse occurs when an observer passes through the shadow cast by the moon which fully or partially blocks the sun . This can only happen when the sun , moon and earth are nearly aligned on a straight line in three dimensions during a new moon . When the moon is close to the ecliptic plane .

Answer 2

Rotary Motion

Rotary motion is anything that moves in a circle. This type of motion was among the first discovered in ancient times. Think of a spinning wheel on which people spun wool. A car's engine works the same way. Like linear cylinders, rotary actuators are used across a wide range of industries and come in electric, pneumatic and hydraulic options.

Oscillating Motion

Something that oscillates moves back and forth. Anything that repeats the motion cycle after a certain period is considered to be oscillating. This type of motion is found everywhere in our world: a sprinkler system, the pendulum of a clock or even sound waves.

You may be thinking that a rotary actuator functions as an oscillating device, and for that matter, so does a linear one when it repeats a continuous movement. When it comes to actuators, linear and rotary can be viewed as oscillating.

Linear Motion

Simple enough, linear motion is anything that moves in a straight line, like our linear actuators. Time, as far as we know, moves in a linear fashion. Just like rotary devices, you can find linear cylinders in electric, pneumatic or hydraulic options. They have driven the field of automation, manufacturing, robotics and others into a new age, because in the past, rotary motion was the only means to create motion.

solar eclipse is an  eclipse in which the sun is obscured by the moon
