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

• Cutting: Using tools like shears, lasers, or plasma cutters to cut the metal sheets into desired shapes

• Bending: Utilizing press brakes to bend the metal sheets at specific angles

• Assembling: Joining the bent and cut metal sheets together using techniques like welding or fasteners

• Finishing: Applying coatings or finishes ...read more

Types of tolerances include bilateral, unilateral, limit, and fit tolerances.

• Bilateral tolerance: Allows for variation in both directions from the nominal dimension.

• Unilateral tolerance: Allows for variation in only one direction from the nominal dimension.

• Limit tolerance: Specifies the maximum and minimum acceptable limits for a dimension.

• Fit tolerance: Determines the acceptable range of tightness or looseness between

Factor of safety is a design parameter that accounts for uncertainties in material properties and loading conditions.

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

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

• Higher factor of safety values indicate a more conservative design approa...read more

Tolerance refers to the allowable variation in dimensions or properties of a part or product.

• Tolerance is important in engineering to ensure proper fit and function of components.

• It is typically specified as a range of acceptable values, such as +/- 0.1mm.

• Tolerance can be applied to dimensions, material properties, surface finish, etc.

• For example, a hole may have a tolerance of +/- 0.05mm to allow for proper alignment

Runge Kutta method is used for numerical solutions of ordinary differential equations.

• Numerical method for solving initial value problems in differential equations

• More accurate than Euler's method

• Commonly used in engineering and physics simulations

• Examples: RK2, RK4, RK45

Hooke's law states that the force needed to extend or compress a spring by a certain distance is proportional to that distance.

• Describes the relationship between the force applied to a spring and the resulting displacement

• Mathematically represented as F = kx, where F is the force, k is the spring constant, and x is the displacement

• Used in mechanical engineering for designing springs, shock absorbers, and other elastic
