WebAug 7, 2024 · Either way, the magnitude of the moment of the force, also known as the torque, is r F sin θ We can regard it as a vector, τ, perpendicular to the plane of the paper: (3.2.1) τ = r × F Now let me ask a question. Is it correct to say the moment of a force with respect to (or “about”) a point or with respect to (or “about”) an axis? WebScalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and …
3.2: Moment of Force - Physics LibreTexts
WebThe moment is a cross product of force F → and perpendicular distance from the point to the force vector r →. A Cross (vector) product is a vector. The moment requires direction … Web4 Answers. Sorted by: 17. It's defined as a dot-product (or scalar product) of force and displacement, both of which are vectors. A scalar product of two vectors gives a scalar result (aptly named!). d W = F → ⋅ S → = ‖ F ‖ ‖ S ‖ cos θ. ( θ being the angle between the vectors). No direction, only magnitude.

Question: Force F acts at the end of the angle bracket in the Figure. Determine the moment of the force about point O by: a. Scalar analysis b. Vector analysis. solve clearly. points will be given. WebSep 11, 2024 · The dot product is known as a scalar product and is invariant (independent of coordinate system). An example of a dot product in physics is mechanical work which is the dot product of force and distance: (14.5.7) W = F → ⋅ d →. The cross product is the product of two vectors and produce a vector.
