The man at B exerts a force of P =50 lb on his rope. The angle theta = 40 deg, h_1 = 9 ft, and h_2 = 12 ft Determine the magnitude of the force the man at C must exert to prevent the pole from rotating. i.e., so the resultant moment about A or both...

to be a particle), as shown in Figure 3-1(a). The string b exerts a force of 30 Ib upon the ring; the string c exerts a force of 50 Ib upon the ring. What force must be exerted by the string a if the ring is to remain in equilibrium? From experience we know that a taut string exerts a force directed along its own length.

The pull such a flexible connector exerts is a tension. Note that the rope pulls with equal force but in opposite directions on the hand and the supported mass (neglecting the weight of the rope). This is an example of Newton’s third law. The rope is the medium that carries the equal and opposite forces between the two objects.

The mass of 220 lb football has less than 288 lb football. So, it will be easier to move it since it will require less force. The heavy football will have a bigger momentum. Since 288 lb has more weight than 220 lb, it will have bigger inertia making it difficult for the players to stop it.

Dec 21, 2020 · The moment of a force about a point is the magnitude of the force multiplied by the perpendicular distance between the force and the point. When 2 forces act in opposite directions, this is known as a couple and the magnitude of the twisting force or couple is called torque.
