Which of the following statement is true?
For two vectors defined by an arrow with a head and a tail. The length of each vector and the angle between them represents:
If a vector is multiplied by a scalar:
All the vectors quantities obey:
a)
The magnitude of the resultant of the two vectors is always_____________
If two equal vector forces are mutually perpendicular then the resultant force is acting at which angle as compared to one of the vector?
What is the direction of the resultant vector if two vectors having equal length is placed in the Cartesian plane at the origin as, one being parallel to and heading towards positive x-axis and the other making 165 degree with it and heading in the opposite direction of that of the first one?
If the resolved force or the force which you get as the answer after solving the question is negative, then what does this implies?
An electromagnet crane is carrying the electromagnet with the help of the three cables. But the electromagnet is not stable because of the wind. What is science behind the cause?
If anybody is tied to three or more ropes, and then is allowed to achieve its equilibrium. Then the equilibrium achieved is achieved w.r.t what?
What does the moment of the force measure?
If a car is moving forward, what is the direction of the moment of the moment caused by the rotation of the tires?
The tendency of rotation of the body along any axis is also called ___________
a)
If the rotation is clockwise in this page, suppose, then in which direction will the thumb project if you curl your hand in the same direction of the rotation?
What does Newton’s third law states?
Which of the following is correct?
a)
For the conditions of the equilibrium of the body, i.e. the rigid body only the external forces defines the equilibrium. Because the internal forces cancels out so not to be considered.
If the body is in equilibrium, but it having a rotational curled ray shown in the free body diagram then:
The difference between the two and the three force members is:
Which of the following is correct?
Which of the following statement for the three force system is true?
All the forces need to be collinear in the three force system. Then only they will for the equilibrium state.
We first make equilibrium equations of the body by considering all the three dimensional forces and then the free body diagram is made and solved.
The supports in the 3D are having more than three reaction forces. Because they are having three axis on which the components of the forces need to be zero.
If the supports are not properly aligned then the reaction forces developed are adequate to support the body.
a)
