Mr. M is opening a physics help center! The sign looks like this The mass of his sign is 82.0kg. If the sign is equilibrium: (a) What is the force of tension in the rope? (b) How much force does the rod have to exert to keep the sign where it is?

Even when the head is held erect, as shown in the figure, its center of mass is not directly over the principal point of support (the atlanto-occipital joint, Point A). The muscles at the back of the neck should, therefore, exert a force to keep the head erect. That is why your head falls forward when you fall asleep in the class. If the head weighs 55 N, calculate the force exerted by the muscles FM using the information in the figure. Assume that 5.1 cm, x2 2.5 cm, and Fw = 55 N. X1 = -26.96 A F N M = Incorrect M What is the force Fj exerted by the pivot on the head? -81.96 Fj = N Incorrect

number 4

I need help please

The 20kg flowerpot is supported at A by the three cords.(a) Determine the magnitude of the force acting in cord AB for equilibrium.  (Express your answer using three significant figures and in N)(b) Determine the magnitude of force acting in cord AC for equilibrium.  (Express your answer using three significant figures and in N)(c) Determine the magnitude of force acting in cord AD for equilibrium.  (Express your answer using three significant figures and in N)

10kg rigid beam that is 3mlong is supported at each end. An8kg block is placed 2m fromsupport 1. How much upward forcedoes each support provide to ensurezero acceleration and zero torque?Note, if an object is not rotating, itis not rotating about every axis.

Unlike most of the other muscles in our bodies, the masseter muscle in the jaw, as illustrated in as shown, is attached relatively far from the joint, enabling large forces to be exerted by the back teeth. (a) Using the information in the figure, calculate the force exerted by the lower teeth on the bullet. (b) Calculate the force on the joint.

A uniform picute frane weighing 10.0 N is supported as shown in the image, where the right side cable makes an angle of 50 degrees with the horizontal direction. Find the tension in the cords and the magnitude of the horizontal force F required to hold the frame in the position shown.

help pls asap not in scientific notation pls

A shop sign weighing 195 NN hangs from the end of a uniform 180180-NN beam as shown in (Figure 1). A. Find the tension in the supporting wire (at 35.0∘∘). B. Find the horizontal force exerted by the hinge on the beam at the wall. Express your answer to three significant figures and include the appropriate units. Enter positive value if the direction of the force is to the right and negative value if the direction of the force is to the left.
