Forces of 67.2lb and 57.3lb are exerted at an angle of 47 degrees. What is their resultant?
Show us what you have done first. How do you add these forces?coolone_888 said:Forces of 67.2lb and 57.3lb are exerted at an angle of 47 degrees. What is their resultant?
Draw a vector diagram. Place one vector along the x axis. The other 47 degrees from the axis with its tail on the head of the first. Draw the resultant. What is the component of the second vector in the y direction? What is its component in the x direction? Add the x components to get the x component of the resultant. What is the y component of the resultant?coolone_888 said:well i know you use c2=a2+b2-2ab cos C. but then I am not sure what to do next.
The resultant is the overall or net effect of two or more forces acting on an object. It is the vector sum of all the forces.
To find the resultant using vectors, you will need to first determine the magnitude and direction of each individual force. Then, add all the forces together using vector addition. The resulting vector will be the resultant.
Yes, trigonometry can be used to find the resultant. You will need to break down each force into its x and y components, and then use sine and cosine to find the resulting x and y components of the resultant. Finally, use the Pythagorean theorem and inverse trigonometric functions to find the magnitude and direction of the resultant.
No, the resultant can be in any direction depending on the magnitude and direction of the individual forces. It is not always in the same direction as the largest force.
Yes, the resultant can be zero if the forces acting on an object are equal and opposite. This is known as equilibrium, where the net force on the object is zero and it remains at rest or moves with constant velocity.
