A uniform 37.0 kg scaffold of length 6.4 m is supported by two light cables, as shown below. An 82.0 kg painter stands 1.0 m from the left end of the scaffold, and his painting equipment is 1.3 m from the right end. If the tension in the left cable is twice that in the right cable, find the tensions in the cables (in N) and the mass of the equipment (in kg). I don't understand how to find mass of the equipment.
A beam of mass 40.0 kg is supported by a cable and attached to a wall as shown in picture. Find the tension T int the cable and the magnitude of force ,F exerted by the wall on the beam.
When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure a. The total gravitational force on the body, F, is supported by the force g' n exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure b, where T is the force exerted by the Achilles tendon on the foot and R is the force exerted by the tibia on the foot. Find the values of T, R, and 0 when F = n = 780 N. (For 0, enter the smaller of the two possible values between 0° and 90°.) -Achilles tendon Tibia 15.0° 18.0 cm 25.0 cm b T = R =
A uniform 50-kg scaffold of length 7.0 m is supported by two light cables, as shown below. A 61-kg painter stands 1.0 m from the left end of the scaffold, and his paint bucket is 1.5 m from the right end. If the tension in the left cable is twice that in the right cable, find the tensions in the cables and the mass of the bucket. m bucket = kg T (left) = N T (right) = N

Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the surface of the door. One child pushes with a force of 18.5 N at a distance of 0.625 m from the hinges, and the second child pushes at a distance of 0.47 m. a) What is the magnitude of the force, in newtons, the second child must exert to keep the door from moving? Assume friction is negligible. F2 =

The diagram shows a sign that wighs 50 N hanging from a uniform horizontal pole. The pole weighs 30 Newton's and it is 1.6 m long. Determine the tension in the supporting cable C and the magnitude and direction of the two component forces at the pivot, P, exert on the pole.
When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure a. The total is supported by the force n exerted by the floor on the toes of one foot. A mechanical gravitational force on the body, F model of the situation is shown in Figure b, where T is the force exerted by the Achilles tendon on the foot and R is the force exerted by the tibia on the foot. Find the values of T, R, and 0 when F, = n = 770 N.
