Determine the moment produced by the force F in fig. 3—14a about point O. Express the result as a Cartesian vector. SOLUTION As shown in Fig. 3—14a, either r A or can be used to determine the moment about point O. These position vectors are rA = {12k} m and = {4i + 12j} m Force F expressed as a Cartesian vector is {4i + 12j - 12k} m = 2 kN

The resultant force is directed along the positive y axis and has a magnitude of 1500 n. The resultant force is directed along the positive y axis and has a magnitude of 1500 n. The resultant force is directed along the positive y axis and has a magnitude of 1500 n.

Answer: C [ Principle transmissibility of the force ] Description: If a force is applied at any point in its line of action and is still creating the same moment about any fixed point, say P, then the force is said to be a sliding vector. This is because the moment of the force which is acting on its line of the axis at point P is the same throughout. It is known as the principle ...

The cable BC exerts an 8 kN force F on the bar AB at B. a) Determine the components of a unit vector that points from B toward point C, b) Express F in terms of components. View Answer

a) The moment of inertia of the system about the z axis and b) The rotational energy of the system. Centripetal acceleration at point P: Tangential acceleration at point P: The distances of the masses to the rotation axis is same. r 1 =r 2 =r 3 =r 4 =r The moment of inertia of the system about the z axis.

The resultant force is directed along the positive y axis and has a magnitude of 1500 n

If there is a force passing through the x,y,z point (-5,14, -7) with a magnitude of 27N, determine the moment it creates on that point. View Answer Consider a …

Example: Problem 5.9 Find the magnetic field at point P for each of the steady current configurations shown in Figure 5.3. a) The total magnetic field at P is the vector sum of the magnetic fields produced by the four segments of the current loop. Along the two straight sections of the loop, and are parallel or opposite, and thus .Therefore, the magnetic field …

Quantitatively, the stress is expressed by the Cauchy traction vector T defined as the traction force F between adjacent parts of the material across an imaginary separating surface S, divided by the area of S.: p.41–50 In a fluid at rest the force is perpendicular to the surface, and is the familiar pressure.

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies.
