To determine the resultant of two forces, one of 60N and the other of 80N, using the tail-to-tail method, follow these steps:
Step 1: Draw a straight line to represent the first force of 60N. Label the starting point as 'A' and the ending point as 'B'. This line represents the direction and magnitude of the first force.
Step 2: Choose a suitable scale and draw another straight line to represent the second force of 80N. Make sure this line starts from the endpoint 'B' of the first force. Label the starting point as 'B' and the ending point as 'C'. This line represents the direction and magnitude of the second force.
Step 3: Complete the parallelogram by drawing lines that connect points 'A' and 'C', and 'B' and 'D'. The lines 'AD' and 'BC' should be parallel.
Step 4: Draw the diagonal line that passes through point 'E'. This line represents the resultant force, which is the vector sum of the two forces.
Step 5: Measure the magnitude of the resultant force using a ruler or scale. In this case, the magnitude is given as 122N.
Step 6: Measure the angle that the resultant force makes with the first force, using a protractor or angle measuring tool. In this case, the angle is given as 25°.
Therefore, the resultant of the two forces, using the tail-to-tail method, is 122N at an angle of 25°.
To determine the resultant of two forces using the tail-to-tail method, follow these steps:
1. Draw a reference line or axis where you will represent the forces.
2. Start by drawing the first force as an arrow. The length of the arrow represents the magnitude of the force, and the direction of the arrow represents the direction of the force. Label this force as Force 1.
3. From the tip of Force 1, draw the second force as another arrow. Again, the length of the arrow represents the magnitude, and the direction represents the direction. Label this force as Force 2.
4. Connect the tail of Force 1 to the tail of Force 2 with a vector arrow representing the resultant force. The length and direction of this arrow will represent the magnitude and direction of the resultant force.
5. Measure the length of the resultant arrow using a ruler. This length represents the magnitude of the resultant force.
6. Measure the angle between the reference line and the resultant arrow. This angle represents the direction of the resultant force.
In your case:
Force 1 has a magnitude of 60 N.
Force 2 has a magnitude of 80 N.
Sketch the forces by drawing an arrow for Force 1 with a length representing 60 units. Then, draw another arrow for Force 2 next to Force 1 with a length representing 80 units. The angle between the reference line and the resultant arrow is 25°.
Now, to determine the magnitude and direction of the resultant force:
1. Measure the length of the resultant arrow using a ruler. In your case, the length is 122 units.
2. Measure the angle between the reference line and the resultant arrow. In your case, the angle is 25°.
Therefore, the magnitude of the resultant force is 122 N, and the direction is 25° with respect to the reference line.
