Q1. What is a random cylinder?
Ans. 
A random cylinder is a geometric shape defined by a random height and radius, often used in probability and statistics.
• A random cylinder can be defined by its height (h) and radius (r), which can vary randomly.

• In probability, random cylinders can model real-world phenomena, like the distribution of particles in a volume.

• Example: If the height of a cylinder is uniformly distributed between 1 and 10 units, and the radius...read more

Q2. What does OEE stand for, and how is it measured?
Ans. 
OEE stands for Overall Equipment Effectiveness, a metric used to measure manufacturing productivity.
• OEE is calculated using three components: Availability, Performance, and Quality.

• Availability = (Operating Time / Planned Production Time) x 100%. Example: If a machine runs for 8 hours but is down for 1 hour, availability is 87.5%.

• Performance = (Actual Output / Maximum Possible Output) x 100%. Example: If a machine prod...read more
