Homework Statement
The Attempt at a Solution
I tried to find the acceleration using F= ma
Resultant force = Tension - mg
so a = (10295.2-8730)/890 = 1.758 m/s^2 but I don't think it works that way...
please help.
Equilibrium is a state of balance or stability in a system where the forces acting on the system are equal and opposite, resulting in a net force of zero.
To calculate the equilibrium of a system, you must first identify all the forces acting on the system and their directions. Then, use the equations of motion (Newton's laws) to find the net force and determine if it is zero. If the net force is not zero, the system is not in equilibrium.
An impulsive force is a force that acts on a system for a very short period of time, resulting in a sudden change in the system's velocity. It is often represented by a delta function in mathematical equations.
In a crane, equilibrium is maintained by the counterweights and the tension in the cables, which balance out the weight of the load being lifted. Impulsive forces are used to initiate movement, such as when the crane operator starts the motor to lift the load.
In the demolition ball problem, the crane and the ball are in equilibrium when the ball is stationary and the tension in the cable is equal to the weight of the ball. When the crane operator releases the ball, an impulsive force is created as the ball falls, resulting in a sudden change in velocity. The equilibrium is then maintained again once the ball reaches the ground and comes to a stop.
