Question:
The rigid metal strip of negligible weight is used as part of an electromagnetic switch. Determine the maximum stiffness k of the springs at A and B so that the contact at C closes when the vertical force developed there is F. Originally the strip is horizontal as shown.
Units Used:
mN 10− 3 = N
Given:
a = 50 mm
b = 50 mm
c = 10 mm
F = 0.5 N
k B C A k
Step by Step Answer:
N Initial Guesses k 1 Give...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
