An electric post is supported by a guy wire which exerts a pull of 100N on the top of the post. If the angle between the guy wire and the ground is 60 degrees, determine the vertical component of the force supporting the pole

(c) Find the vertical force exerted on the base of the rod. Ignore the weight of the rod. magnitude _____ N direction _____ upwards or downward?

- 5. Two identical, uniform beams of length 3 m and weighing 260 N each are connected at one end by a frictionless hinge. A light horizontal crossbar, attached at the midpoints of the beams maintains an angle 50° between the beams. The beams are suspended from the ceiling by vertical wires so they form a V. See figure. (a) What force does the crossbar exert on each beam? (b) Is the crossbar under compression or tension, i.e. are the ends of the crossbar being pushed together or stretched farther apart? (c) What force (magnitude and direction) does the hinge exert on each beam? Crossbar Hinge

A beam of weight 1500 N is hinged at one end to the wall. The beam makes an angle of 37° with the wall. Its other end is attached to the wall with a cable making an angle of 53° with the wall. a) Find the tension in the cable. b) Find the magnitude of the force at the hinge. उने T 53 37% V12

The system is in equilibrium.  A concrete block of mass 225 kg hangs from the end of the uniform strut whose mass is 45.0 kg.  Find the tension in the cable and the horizontal and vertical forces on the strut from the hinge

The weight of the homogeneous rod is 500N and its length is 5m Find the angle of inclination of the weight of the homogeneous rod that will keep it in equilibrium on the smooth surfaces on which it is placed хθ the rod from the horizon

The mass of the uniform bar AB is100 gram. Calculate the couple C required for equilibrium if the angle is 60 degrees.

A 387-kg steel beam of length 5.00 m is attached to a wall by a hinge, and kept level by a cable attached to it at a 30.0◦ angle. The maximum tension that the cable can sustain before breaking is 13.0 kN. There is a support that allows a mass to be hung from the beam, three-quarters of the way along its length. (a) What is the maximum mass that can be hung from the beam before the cable snaps? (b) At this maximum mass, what is the magnitude and direction of the reaction force F from the wall against the hinge?
