Each of the identical steel balls weighs 4 lb and is fastened to the other two by
Question:
Each of the identical steel balls weighs 4 lb and is fastened to the other two by connecting bars of negligible weight and unequal length. In the absence of friction at the supporting horizontal surface, determine the initial acceleration a̅ of the mass center of the assembly when it is subjected to the horizontal force F = 20 lb applied to the supporting ball. The assembly is initially at rest in the vertical plane. Can you show that a̅ is initially horizontal?
F
Step by Step Answer:
To determine the initial acceleration of the mass center of the assembly we can analyze the forces acting on it and apply Newtons second law of motion ...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.
