Calculate the normal force in A in the bar and pulley system
shown. In O there is a "pin". Assume that the surface at A is
smooth or smooth. The mass value of the cylinder (m1) is equal to
20 kg. Evaluate the normal force at A for values of m1 (cylinder
mass) from 10kg to 60kg at intervals of 10 (6 cases). Make a graph
of Normal vs. cylinder mass (Normal in y / Mass in x). It is...
The tail of the Earth's magnetic field is stretched by the
solar wind so that the north field is still pointing
moving away from the earth and the south field pointing towards the earth.
The magnetic field at that distance has a density value of
magnetic flux about 0.25 Gauss. The space is the same
medium on both sides of the magnetic field but the fields do not
they can exist that way without a current sheet. If
you assume...
Only 2 and 5
2. Three spheres of 5.00 kg each are separated by the
distances d1 and d2 as shown in the figure. Calculate the force of
attraction, in vectorial representation, if the distances are d1 =
0.300
-? -? m and d2 = 0.400m. Ans: ? = ?.?? × ??^-8 ?? + ?.?? ×
10^-6
5. At what altitude on the surface of the Earth, the
acceleration of gravity would have a value of 4.9 m / s2?...
the figure shows a section of the alpine system of wagons moved
by the section of a cable. The maximum permitted mass of each wagon
with occupants is 2800 kg. The wagons, which travel on the support
cable, are pulled by a second cable from a tower. What is the
voltage difference between the two adjacent sections of the
traction cable if the wagons are accelerated upwards at a rate of
0.81 m / s2 and an inclination of 35...
