PROBLEM 2.F4
A chairlift has been stopped in the position
shown. Knowing that each chair weighs 250
N and that the skier in chair E weighs 765 N,
draw the free–body diagrams needed to
determine the weight of the skier in chair F.
PROBLEM 2.F5
Three cables are used to tether a balloon as shown. Knowing that
the tension in cable AC is 444 N, draw the free–body diagram
needed to determine the vertical force P exerted by the balloon at
A.
PROBLEM 2.F6
A container of mass m = 120 kg is supported by three cables
as shown. Draw the free–body diagram needed to determine
the tension in each cable
PROBLEM 2.F7
A 150–lb cylinder is supported by two cables AC and BC that are
attached to the top of vertical posts. A horizontal force P, which
is perpendicular to the plane containing the posts, holds the
cylinder in the position shown. Draw the free–body diagram
needed to determine the magnitude of P and the force in each
cable.
PROBLEM 2.F8
A transmission tower is held by three guy wires attached
to a pin at A and anchored by bolts at B, C, and D.
Knowing that the tension in wire AB is 630 lb, draw the
free–body diagram needed to determine the vertical force
P exerted by the tower on the pin at A.
