Mathematically solve for the Force applies to hold a pendulum bob stationary 0.15 m away from the vertical axis as it’s being held by a 4.0 m string attached to a ledge. The mass of the bob is 30 kg
To solve for the force applied to hold the pendulum bob stationary, we need to consider the gravitational force acting on the bob.
The gravitational force, Fg, is given by the equation Fg = mg, where m is the mass of the bob and g is the acceleration due to gravity.
In this case, the mass of the bob, m, is 30 kg, and the acceleration due to gravity, g, is approximately 9.8 m/s^2.
So, Fg = (30 kg)(9.8 m/s^2) = 294 N.
The force required to hold the pendulum bob stationary is equal to the gravitational force acting on it. Therefore, the force applied to hold the pendulum bob stationary is 294 N.
