Question

A 5.0 kg uniform bar 2.0m long is suspended horizontally by two vertical wires: the first is attached at position 0.0cm and the second is at the 150cm position. The tension in the second wire is __________

Answer #1

A 9.0 kg uniform bar 2.0m long is suspended horizontally by two
vertical wires: the first is attached at position 0.0cm and the
second is at the 150cm position. The tension in the second wire is
__________(include units).

A uniform steel beam (mass 43.7 kg, length 9.79 m) is hinged at
one end to a wall and has two wires attached at the other end. Wire
1 (length 4.67 m) is horizontal and is attached to the wall, and
wire 2 is vertical and is attached to the floor If the system is in
equilibrium and the tension in wire 2 is 130 N, find the magnitude
of the tension in wire 1, in
N.

Two 1-meter long vertical, parallel wires 12.5 cm apart each
carry a current. The first wire carries 31 Amps upward. If it
exerts an attractive force of 5.1 x 10- 4 N on the second wire,
what is the magnitude and direction of the current in the second
wire?

A bar of uniform cross section is 28.1 in long and weighs 61.2
lb. A weight of 67.3 lb is suspended from one end. The
bar and
weight combination is to be suspended from a
cable attached at the balance
point. How far (in) from the weight
should the cable be attached, and what is the tension (lb) in the
cable?

A 2.4 m swinging chair is suspended from the ceiling by two
vertical ropes that are connected to each end. The swinging chair
has a uniform mass of 15 kg. Suppose you have a mass of 65 kg, and
want to sit at a position 0.6 m from one end of the swing. What is
the tension in each of the two ropes?

A bar of length L and uniform density is held horizontally
against a wall by a pivot at one end and a rope of tension T which
pulls up and to the left making an angle \theta with the vertical
wall. The rope is attached to the bar at a distance l = \frac{1}{3}
L from the wall. A mass M is resting at the end of the bar.If the
bar has total mass 2.6kg, the mass M=2.6kg, and the...

A block weighing w newtons is suspended from a horizontal
support by two wires. The first wire extends up and to the left
from the block, making a 41 degree angle with the horizontal
support. A vector extending from the block along the first wire is
labeled F 1. The second wire extends up and to the right from the
block, making a 31 degree angle with the horizontal support. A
vector extending from the block along the second wire...

10.0-m long bar is attached by a frictionless hinge to a wall
and held horizontal by a rope that makes an angle 53 degrees with
the bar. The bar is uniform and weighs 39.9 N.
How far from the hinge should a 10.0-m Kg mass suspended from
the tension T in the rope to be 125 N?

If a traffic light is stationary at a 4-way, and is suspended
from two wires one at a 53 degree angle and the second at a 37
degree angle relative to the horizontal, find the tension in two
wires which support a traffic light if the mass of the traffic
light is 30-kg.
Please list any formulas used

A ball hangs from two wires the left wire makes 60 deg angle
with vertical and the tension in wire is 326 N . The right wire
makes 45 deg angle with vertical. Calculate the mass of ball in kg,
take g = 9.8 m/s^2 , answer should be to two significant digits
.
