What is the dimension of stress?
it is the dimension of force over dimension of area. stress = force/area Why, that's just pressure !
What is dimension of power?
The dimension of power is (energy / time)= (force x distance) / time= (mass x distance / time2) x distance / time= mass x distance2 / time3= ML2T-3
What do you calculate to find a moment?
force x perpendicular distance from a specific, defined point
Weight x distance divided by time?
Weight has same dimension and unit as force. Distance has same dimension and unit as displacement. So weight * distance has same dimension and unit as force * displacement. Force * displacement is work done by the force. Work divided by time to do the work is Power. So weight * distance divided by time also has same dimension and unit as Power although it is not power. S.I. unit of weight * distance divided by time is Newton *meter/second or Nms-1 (in abbr.) It's dimensions are 1, 2, -3 in mass, length and time respectively. Note that given quantity's unit can't be joule/second or watt because weight * distance is not work done, only unit and dimension are same1 . 1. Two physical quantities may have same dimensions and units but that doesn't mean they refer to same quantity.
What is the dimension of strain?
it has no dimension
What is dimension of moment of force?
The SI unit is the newton-metre, the imperial the foot-pound. For more information please see the wikipedia article.
What is the dimension of stress?
it is the dimension of force over dimension of area. stress = force/area Why, that's just pressure !
Is the dimension of the frequency match the dimension of the force?
no ! dimensions of force and that of frequency are different.
What is the dimension of moments of force?
Moments of force are typically described in units of torque, which have dimensions of force times distance. Therefore, the dimensions of moments of force can be expressed as distance multiplied by force, such as in Newton-meters (Nm) or foot-pounds (ft-lb).
How do you work out the moment?
To work out the moment of a force you times the force by the distance the force is from the pivot. So, basically: Moment = force x distance.
What is the dimension for moment of inertia?
The dimension for moment of inertia is typically expressed as mass multiplied by length squared (kg*m^2). It represents an object's resistance to change in its rotational motion.
When calculating moment of force what two changes can be made to increase the size of the moments?
To increase the size of the moment of force, you can increase the magnitude of the applied force or increase the distance from the pivot point at which the force is applied. Both of these changes will result in a larger moment of force.
What is the dimension of moment of inertia?
The dimension of moment of inertia is mass multiplied by distance squared, typically measured in units of kg.m^2.
What can change when moment changes?
moment depends upon the force and the perpendicular distance between the force and the point where we are finding the moment. so when moment changes either the force will change or the perpendicular distance will change.
Since a moment is a force times a distance is it true to call a moment a force?
No, a moment is a force x a distance, it is the product of a force and a distance. You get the same moment with a force of say 2 Newtons at 0.5 meter as a force of 1 Newton at 1 meter, so it is obviously not a force alone, but the product of a force and a distance, and its units are Newton.meters in the SI system
How do you calculate the moment force about the pivot?
To calculate the moment force about a pivot, you multiply the force applied by its distance from the pivot. The formula is: Moment force = Force × Distance. Make sure to consider the direction of the force and apply the right-hand rule for the vector direction.
What will be the shear force when bending moment is constant?
On SFD's and BMD's: The shear force will be 0, the shear force is the derivative of the bending moment at a point on shear force and bending moment diagrams. Otherwise: It depends on the loading.
