Strain energy is defined as the energy stored in a body due to deformation. The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation.
Two physical science classes are playing tug of war. Mrs. Hankinson’s class pulls left with a force of 100 N, while Mrs. Wade’s class pulls with a force of 105 N in the opposite direction.
What is the net force, and which class won?
A. 205 N, Mrs. Wade's class
B. 5 N, Mrs. Wade's class
C. 205 N, it was a tie
D. 5 N, Mrs. Hankinson's class
The net force is 5 N and the class that won is Mrs. Wade's class (Option B)
How do I determine the net force?We can obtain the net force by using the following formula:
Net force = Opposite force - force of pull
Now, we shall determine the net force as illustrated below:
Force by Mrs. Hankinson’s class = 100 NForce by Mrs. Wade’s class = 105 NNet force =?Net force = Opposite force - force of pull
Net force = Mrs. Wade’s class - Mrs. Hankinson’s class
Net force = 105 - 100
Net force = 5 N
From the above calculation, we can say that the net force is 5 N and the class that won given the above data is Mrs. Wade’s class
Therefore, the correct answer to the question is:
5 N, Mrs. Wade's class (Option B)
