What is resultant torque of a couple?
if like parallel forces and unlike parallel forces acts on body at same time what is their resultant force and resultant torque
Give an example of a case when the resultant force is zero but resultant torque is not zero?
A couple.
What is An example of case when resultant force is zero but torque is not zero?
[object Object]
What is an example when resultant force is zero but resultant torque is not zero?
A couple: 2 parallel forces equal in magnitude, but opposite in direction separated by a distance.
How do you know if the system is in equlibrium?
A system is in equilibrium if: 1. The resultant force on it is zero. 2. The resultant torque on it is zero. Note that for a system which is a point object, only condition 1 is necessary for the system to be in equilibrium.
What 2 things does the moment of a force depend on?
What two factors must be known in order to calculate the moment of a force? Torque = Force * distance Torque and distance must be perpendicular to each other If not you must determine the portion of the torque that is perpendicular.
How does the equilibrant force compare with the resulltant force?
The resultant is a trigonometric function, usually using the Law of Cosines in two dimensional solution by vector resolution, of two or more known forces while equilibrant is equal in magnitude to the resultant, it is in the opposite direction because it balances the resultant.Therefore, the equilibrant is the negative of the resultant.
Is resultant a vector quantity?
The resultant of two vectors cannot be a scalar quantity.
Which motion does a couple produce?
It has a resultant moment but does not have resultant force.
How to find resultant force?
To find the resultant force you need to find both the x and y component of the resultant force. Once you have that, you can use the Pythagorean theorem to find the resultant force.
Why is the relationship between torque horsepower and RPM not linear In automobile terms.?
It is, Horsepower = Torque x RPM, but Torque is not constant across the rev range of an engine. For gasoline engines, there is generally very little torque at low rpms, generally flat torque across the middle rpms, and then a drop off as the engine starts spinning too fast for complete combustion. Electric engines, on the other hand, start off with maximum torque and decrease with higher engine speed. So, the short answer to your question is that it's a direct relationship between horsepower and torque, but the variation in the torque curve across the rpm range makes the resultant horsepower curve vary too. (If your question was really why does torque vary with rpm, simply stated it's because engines have varying efficiencies at different speeds.)

A resultant vector is?
a resultant vector not only the resultant of two or three vector. it is the resultant direction of two or many vectors.(let us push an object with same force in opposite direction the resultant is zero and if we push in same direction the force will double.if we pull a object with same force in x and y direction the resultant force in 45 degrees to x axis)
