In
another version of the "Giant Swing," the seat is connected to two
cables as shown in the figure
(Figure
1),
one of which is horizontal. The seat swings in a horizontal circle
at a rate of 36.1
.
A) If the seat weighs 278
and a 869-
person is sitting in it, find the tension
in the horizontal cable.
B)If
the seat weighs 278
and a 869-
person is sitting in it, find the tension
in the inclined cable.
Let T1 be a tenson in horizontal one anD T2 in other one
T2cos(40) = (278+869)
T2=1497.3 N
v= (2*3.14*36.1*r)/60 =3.77r = 3.77*7.5 =28.33
1497.3*sin(40)+T1 = (278+869)*28.33^2/7.5*9.8
T1=11596.8
the angular velocity is w = 36.1 rev/min = 36.1 x (2pi/60) rad/s
the weight of seat is W = 278 N
the weight of person is W1 = 869 N
the total weight of seat and person is
F = W + W1
the tension T1 in the horizontal cable is
T1 = F x cosA - m x r x w^2
where A = 40.0o,m = (W +W1/g),g = 9.8 m/s^2 and r = 7.50 m
the tension T2 in the vertical cable is
T2 = F x sinA - m x r x w^2
A) W=36.1 rev/min = 36.1*2*3.14/60 = 3.778rad/s.........
for horizontal T1=r*W^2==========>T1= 107.07N..........
B)for inclined rope
T2 sin 50 = mg =========>T2= mg / sin 50 =(278+869)/sin50=1497.3 N..............

In another version of the "Giant Swing", the seat is connected
to two cables as shown in the figure (Figure 1) , one of which is
horizontal. The seat swings in a horizontal circle at a rate of
30.9 rev/minPart AIf the seat weighs 220N and a 829-N person is sitting in it,
find the tension in the horizontal cable.Part BIf the seat weighs 220N and a 829-N person is sitting in it,
find the tension in the inclined cable.
In another version of the "Giant Swing" (see Exercise 5.50), the
seat is connected to two cables, one of which is horizontal(Figure
1) . The seat swings in a horizontal circle at a rate of 28.0
rev/min. If the seat weighs 255 N and a 825-N person is sitting in
it, find the tension in each cable.
In the system, a ball with 10 Kg connected to two cables, the
inclined cable, and the horizontal cable. It is moving at a
constant speed. The tension on the horizontal is 120 N. Find the
speed.?R=7Degree = 35

In a rescue, a 77.4 kg police officer is suspended by two
cables, as shown in the figure. Cable A makes an angle
?A = 29.0° with respect to the horizontal, and cable B,
?B = 67.0°. Sketch a free body diagram. Calculate the
tension in cable A.

A 18.8 kg traffic light is suspended from two cables as shown in the figure below. Find the tension in each cable in newtons. left cable _______ right cable _______
A uniform 50-kg scaffold of length 7.0 m is supported by two light cables, as shown below. A 58-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. Express all answers rounded to one decimal place.
