Nocti Review Guide

Area of a Circle

A = πr², where A is the area and r is the radius.

Volume of a Prism

V = A × h, where V is the volume, A is the area of the base, and h is the height.

Area of a Triangle

A = 1/2 × b × h, where A is the area, b is the base, and h is the height.

Circumference of a Circle

C = 2πr, where C is the circumference and r is the radius.

Engineering Design Process

A structured approach that includes problem identification, research, prototyping, testing, and implementation.

Functionality

The design's ability to perform its intended purpose.

Efficiency

Minimization of resources and time in the design process.

Aesthetics

The visual appeal of the design.

Sustainability

Designing with environmental impact in mind, ensuring longevity and reduced waste.

Safety

Minimizing potential hazards for users and the environment.

Decision Matrix

A tool used to evaluate and compare multiple design alternatives based on established criteria.

Constraints in Design

Factors such as appearance, functionality, regulations, material availability, time, and cost that limit design choices.

Open Loop System

A system where the output is not fed back into the system.

Closed Loop System

A system where the output is fed back to adjust the system's operation.

Predictive Analysis

Using data, simulations, and modeling to predict design performance before physical testing.

CAD (Computer-Aided Design)

A tool used to create 2D or 3D models of designs.

Orthographic View

A 2D representation showing all sides of an object.

Safety Glasses

PPE required for protection against eye injuries during engineering tasks.

Torque

Torque = Force × Distance, a measure of the rotational force applied.

PPE for Table Saw

Personal protective equipment including safety glasses, hearing protection, dust mask, and appropriate clothing.

Core Principles of Design

Functionality, Efficiency, Aesthetics, Sustainability, Safety, Cost-Effectiveness.
