Considerations for selecting engineering materials, calculating sheer strength of a metal bar, and explaining project work.

• Consider factors like strength, durability, cost, and availability when selecting materials for specific applications.

• Calculate sheer strength of a round cross section metal bar using the formula: Sheer Strength = (0.5 * Ultimate Tensile Strength)

Circularity and circular run out are both measurements of how well a circular object conforms to its intended shape.

• Circularity measures the overall roundness of a circle, while circular run out measures the variation in the center point of the circle as it rotates.

• Both measurements are important in ensuring the proper functioning of rotating parts in machinery.

• For example, in a car engine, circularity ensures that pistons move smoothly within cylinders, while circular run ou...read more

Stress is the force per unit area acting on a material. Formula: Stress = Force/Area

• Stress is a measure of the internal forces in a material

• It is calculated by dividing the force applied to the material by its cross-sectional area

• Stress can be tensile, compressive, or shear

• Examples of stress include the weight of a book on a table, the force of wind on a building, and the pressure of water on a dam

The hole to hole distance with a feature control frame with MMC modifier at a specific diameter is determined by the geometric tolerance specified in the feature control frame.

• The maximum and minimum distances between the holes are determined by the size of the feature control frame and the MMC modifier.

• The MMC modifier allows for the maximum material condition of the part, which affects the allowable tolerance for the feature.

• The feature control frame specifies the geometric...read more

GD&T is a symbolic language used to communicate design specifications and tolerances in manufacturing.

• GD&T stands for Geometric Dimensioning and Tolerancing

• It uses symbols to communicate design specifications and tolerances

• Implementation involves statistical tools and techniques to measure and analyze process performance.

• Organizations often use Six Sigma to increase efficiency, reduce costs, and improve ...read more

Tolerance stackup is the accumulation of variations in dimensions and tolerances in a product design.

• Tolerance stackup occurs when the accumulated variations in dimensions and tolerances of individual components in an assembly result in deviations from the intended design.

• It is important to consider tolerance stackup to ensure that all components fit together properly and meet the required specifications.

• Tolerance stackup analysis involves calculating the cumulative effect of...read more

Bonus tolerance is an additional tolerance allowed beyond the basic tolerance to ensure proper fit and function of parts.

• Bonus tolerance is used to compensate for variations in manufacturing processes or materials.

• It is typically added to the upper limit of the basic tolerance to ensure proper functionality.

• Bonus tolerance is often specified in engineering drawings to ensure parts can still fit together within acceptable limits.

• For example, if a part has a basic tolerance of ...read more

Factor of safety is a design factor used to account for uncertainties and variations in materials, loads, and other factors.

• Factor of safety is the ratio of the maximum stress a material can withstand to the maximum stress it is subjected to in a design.

• It ensures that the structure or component will not fail under normal operating conditions.

• Commonly used in engineering to prevent failure due to unexpected loads, material defects, or other uncertainties.

• For example, if a bri...read more

Sheet metal guidelines are rules and recommendations for designing and manufacturing sheet metal parts.

• Design parts with minimum bends to reduce cost and complexity

• Use standard sheet metal thicknesses to avoid custom tooling

• Add flanges for strength and rigidity

• Avoid sharp corners to prevent cracking during bending

• Design parts with consistent bend radii for uniformity

Sheet metal process involves cutting, bending, and assembling metal sheets to create various products.

• Cutting: using tools like shears, laser cutting, or water jet cutting to cut the metal sheets to the desired shape

• Bending: using press brakes or rollers to bend the metal sheets into the required angles

• Assembling: joining the bent and cut metal sheets together using techniques like welding, riveting, or adhesive bonding

Geometric dimensioning and tolerancing symbols can be used without a datum reference.

• GD&T symbols can be used independently to specify geometric characteristics of a part.

• Examples include flatness, straightness, circularity, and profile of a feature.

• These symbols do not require a datum reference to define the tolerance zone.

• They can be used in conjunction with datums for more precise control of part features.

Design calculations involve determining the dimensions, materials, and specifications needed for a product or system.
