whats mean by bending moment , torque, types of beams, angle of projection , composite materials,

Question

Accepted Answer

Bending moment is the force that causes a beam to bend. Torque is the force that causes an object to rotate. Beams can be classified into different types based on their shape and support. Angle of projection is the angle at which an object is projected. Composite materials are made up of two or more materials with different properties.

Bending moment is the product of force and distance from the force to the point of rotation.
Torque is the product of force and the perpendicular distance from the force to the axis of rotation.
Types of beams include cantilever, simply supported, fixed, and continuous beams.
Angle of projection is important in projectile motion and can affect the range and height of the object's trajectory.
Composite materials can have improved strength, stiffness, and durability compared to single-material structures. Examples include fiberglass, carbon fiber, and reinforced concrete.
