A block of weight w is suspended from a rope tied to two other ropes at point O. One rope ishorizontally attached to a wall and the other is fastened to the ceiling. The angle betweenceiling and the rope is 60°. What are the tensions in each of the ropes? Assume the weights ofthe ropes and the knots are negligible. If the weight of the block is 100 N, what is the tension inthe ceiling rope?

In the design of a supermarket, there are to be several rampsconnecting different parts of the store. Customers will haveto push grocery carts up the ramps and it is desirable thatthis not be too difficult. The engineer has done a survey andfound that almost no one complains if the force requiredis no more than 18 N. Ignoring friction, at what maximumangle θ should the ramps be built, assuming a full 25-kg cart?
A skier is standing on a 30o hill. Draw the hill and add idealized force vectors that represent the force of the skier (FS), the normal force (FN), and the force of friction (FF).
The forces acting onan object weighingW units on aninclined planepositioned at anangle of θ with thehorizontal (see figure)are modeled byμW cos θ = W sin θ,where μ is the coefficient of friction. Solve theequation for μ and simplify the result.
