- A stepladder of negligible weight is constructed as shown with AC = BC = L. A painter of mass m stands on the ladder a distance d from the bottom. Assuming the floor is frictionless, find a) the tension in the horizontal bar DE connecting the two halves of the ladder, b) The normal forces at A and B and c) the components of the reaction force at the single hinge C that the left half of the ladder exerts on the right half. (Suggestion: treat the ladder as a single object, but also treat each half of the ladder separately.) BA uniform 37.0 kg scaffold of length 6.2 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 1.6 mfrom 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). (Due to the nature of this problem, do not use rounded intermediate values in your calculations).A 6.0 m long ladder AB leans against a smooth wall making an angle of 60º with the floor (Figure 3). The ladder is uniform and has a mass of 20.0 kg.(a) Determine the forces exerted on the ladder by the floor and the wall (i.e. at A and B, respectively).(b) Determine the minimum value of the coefficient of static friction to prevent the ladder from slipping.
- A man holds a 195-N ball in his hand, with the forearm horizontal (see the figure). He can support the ball in this position because of the flexor muscle force M , which is applied perpendicular to the forearm. The forearm weighs 20.7 N and has a center of gravity as indicated. Find (a) the magnitude of M and the (b) magnitude and (c) direction (as a positive angle counterclockwise from horizontal) of the force applied by the upper arm bone to the forearm at the elbow joint.

They both increase as increases. They do not depend on 0. The force that the biceps muscle exerts decreases and the force on the elbow joint increases as increases.
- One end of a uniform { = 4.30-m-long rod of weight w is supported by a cable at an angle of 0 = 37° with the rod. The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wall and the rod is µ. = 0.490. Determine the minimum distance x from point A at which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at point A. B Need Help?

- A spool of thread consists of a smaller cylinder of radiusR/2 in the middle and two discs of radius R fixed to its two ends.The thread is wound on the cylinder. The spool of mass m isplaced on a horizontal table, then the end of the thread is pulledin a direction shown in the figure.a) What is the angle α between the thread and the vertical ifthe center of the spool does not move neither to the left nor to theright?
