Welcome to the PF.shady said:Hi , please i want to know if i have flat plate (rectangle) but its fixed like pendulum (fixed from one end and free at the other end and can rotate around this fixed end) i want to know the drag force due to air on this plate?
Drag force is the force that opposes the motion of an object moving through a fluid (such as air or water).
Drag force affects a flat plate pendulum by slowing down its motion and causing it to eventually come to a stop due to the resistance it experiences while moving through the air.
Yes, drag force can be reduced on a flat plate pendulum by adjusting its shape or orientation to minimize the surface area facing the direction of motion, or by increasing the fluid's viscosity.
The magnitude of drag force on a flat plate pendulum is affected by factors such as the object's shape, size, velocity, and the properties of the fluid it is moving through.
Drag force on a flat plate pendulum can be calculated using the formula Fd = 1/2 * ρ * V^2 * Cd * A, where ρ is the density of the fluid, V is the object's velocity, Cd is the drag coefficient, and A is the cross-sectional area of the object.
