What are the three different places on a bridge that would experience different forces?
The three different places on a bridge that would experience different forces are the supports (where vertical forces are highest), the center span (where compression and tension forces are highest), and the connections between bridge sections (where shear forces are highest).
What is the combined total of all forces acting on an object?
that is called the net force; it is a vector sum of all the forces acting on it
Does an object at rest have forces acting on it and if so what forces would be along the vertical axis?
Yes, an object at rest can have forces acting on it. The vertical forces acting on an object at rest would include gravity pulling it downward and the normal force from a surface pushing it upward to balance the force of gravity.
What force or forces would be acting upon a falling airplane?
The main forces acting on a falling airplane are gravity, which pulls it downward towards the ground, and air resistance, which opposes its motion and can slow it down. Depending on the situation, other forces such as wind or turbulence may also affect the airplane's fall.
How would changes in temperature would affect a bridge?
Thermal expansion means that the length of the bridge changes.
What is equilibrant forces?
The force is said to be "equilibrant" when acting with other forces it would keep the body at rest ie in equilibrium. Hence equilibrant would be equal in magnitude but opposite in direction to the resultant of all the forces acting on the body.
What is total of all of the forces on an object?
That would be the net force acting on the object.
How do balance forces acting on an object affect its motion?
When the forces acting on an object are balanced, they cancel each other out and the result is no change in its motion.Balanced forces have no effect on motion. Unbalanced forces cause acceleration.
If a book remains stationary on a table are the forces acting upon the book in equilibrium what is the resultant of the force acting upon the book?
Yes, if a book is stationary on a table, the forces acting on it are in equilibrium. The resultant force acting on the book would be zero, as the forces are balanced and there is no net force causing any acceleration or movement.
What will you get if you draw lines of action of all the forces acting on the board annd extend the line?
By extending the lines of action of all the forces acting on the board and finding their point of intersection, you would get the resultant force on the board. This resultant force represents the overall effect of all the individual forces acting on the board.
This is a depiction of 2 forces acting on a puck (top view). Which direction would a 3rd force have to be to balance the forces?
The third force would need to act in the opposite direction to the resultant of the two initial forces in order to achieve equilibrium for the puck. This can be calculated by finding the vector sum of the two forces acting on the puck.
What are the forces acting when pushing a trolley?
When pushing a trolley, the main forces acting on it are the force of friction between the wheels and the ground, the force of gravity acting downward, and the normal force exerted upward by the ground on the trolley to support its weight. Additionally, if the trolley is on an incline, there will be a component of the gravitational force acting parallel to the incline.
