ANY EXPERTS PLS The figure (Figure 1) shows a model of a crane that may be mounted on a truck. A rigid uniform horizontal bar of mass m1 = 90.0 kg and length L = 6.00 m is supported by two vertical massless strings. String A is attached at a distance d = 1.10 m from the left end of the bar and is connected to the top plate. String B is attached to the left end of the bar and is connected to the floor. An object of mass m2 = 3500 kg is supported by the crane at a distance x = 5.80 m from the left end of the bar.
Throughout this problem, positive torque is counterclockwise and use 9.80 m/s2 for the magnitude of the acceleration due to gravity.

Find TA, the tension in string A.
Express your answer in newtons using three significant figures

The figure (Figure 1) shows a model of a crane that may be mounted on a truck. From the given information, the tension in the string A (TA) is

It is always a good idea to list the parameter given, this will help you highlight the known variables and assist you in finding the unknown variable. Here, we are to find the tension in string A.

From the given information;

The forces acting on the system can be seen in the image attached below.

The net torque applied on the bar is zero at equilibrium.

Using the application of Newton's Law for rotational motion, the net torque acting on the end of the bar can be computed as:

As such, the tension in string A can be determined as:

Therefore, we can conclude that the tension in string A (TA) is
