A 4 m long horizontal uniform beam of mass 24 kg is supported by a wire as shown in the figure. The wire makes an angle of 26 degrees with the beam. Attached to the beam 1.6 m from the wall is a ball with a mass of 57 kg. VWhat is the tension in the string?
From the step ladder shown in the figure, sides AC and CE are each 2.44 m long and hinged at point C. Bar BD is a tie-rod 0.762 m long, halfway up. A man weighing 845 N climbs 1.8 m along the ladder. Assuming the floor is frictionless and neglecting the mass of the ladder, find the tension (in N) in the tie-rod.

A uniform plank of length 2.00 m and mass 26.0 kg is supported by three ropes, as indicated by the blue vectors in the figure below. Find the tension in each rope when a 710–N person is d = 0.500 m from the left end. Answer the 3 boxes below:
in the FIRST CONDITION OF EQUILIBRIUM USING TENSION PROTRACTORS,why should the center weight be less than the sum of the left and right weights?
A meter stick is pivoted at its 50cm mark but does not balance because of non-uniformities in its material that cause its center of gravity to be displaced from its geometrical center. However, when weights of 150g and 300g are placed at the 10cm and 75cm marks, respectively, balance is obtained. The weights are then interchanged, and balance is again obtained by shifting the pivot point to the 43cm mark. Find the mass of the meter stick and the location of its center of gravity.
A uniform ladder 6m long weighs 225N. It leans against a smooth vertical wall, making an angel of 53° with the horizontal ground. If the coefficient of friction between the foot of the ladder and the ground is 0.34, how far up the ladder can a 650N woman climb before the ladder starts to slip?
In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tree 15 m away, as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?
