The shorter legs of two 6”x 4” x 1⁄2” angles are welded
to a 12”-20.7-lb channel. Determine the moments of
inertia of the combined section with respect to
centroidal axes respectively parallel and
perpendicular to the web of the channel.

Expert Solution

Solution) As have to find the centroid and moment of inertia of a given section thus by constructing the section according to the given details in the question and using the section appropriately we can make the section then Centroid can be find out by using the dimensions of the sections. Now to find the moment of inertia of the section along parallel and perpendicular to the web of channel we can use parallel axis theorem as shown in the following solution -

(1 point) A mass weighing 4 lb4 lb stretches a spring 6 in.6 in. The mass is displaced 8 in8 in in the downward direction from its equilibrium position and released with no initial velocity. Assuming that there is no damping, and that the mass is acted on by an external force of 5cos(7t)5cos⁡(7t) lb, solve the initial value problem describing the motion of the mass. For this problem, please remember to use English units: ft, lb, sec.ft, lb, sec....

In Cpp A rational number is a quotient of two integers.For example, 12/5,12/-4,-3/4, and 4/6 are all rational numbers .A rational number is said to be in reduced form if its denominator is positive and its numerator and denominator have no common divisor other than 1 For example,the reduced forms of the rational numbers given above are 12/5, -3/1, -3/4 and 2/3. Write a class called Rational with a constructor Rational ( int, int) that takes two integers, a numerator...

Water flows between two reservoirs through 800 ft of 12-inch diameter welded-steel pipe. The water surface elevation difference between the two reservoirs is 16 ft. Find the flowrate (a) assuming head loss is only due to pipe friction, and (b) Accounting for both friction losses and minor losses due to a flush square-edged pipe entrance, the pipe exit, and a half-open gate valve in the line. Assume the water temperature is 60°F.

There are two charges q1 = 4 x 10^-5 C and q2 = 6 x 10^-5 C with a separating distance of d for 2 m. Calculate the magnitude of the force exerted by these two charges on a new charge Q with 10^-5 C, if it is placed halfway between them. Is there a point between the two charges where the force vanishes? If yes, calculate the location of the point between the two charges. (k = 8.99 X...

A wire bent with two right angles (forming a u-shape) sits in the xy-plane. The closed end (where the right angles are) is on the x-axis.

A wire bent with two right angles (forming a u-shape) sits in the xy-plane. The closed end (where the right angles are) is on the x-axis. The sides parallel to the y-axis run in the -y direction. A movable wire, parallel to the x-axis but not on the x-axis at any time, moves in the +y direction. If a magnetic field going in the -z direction baths the circuit, what is the direction of the induced current in the movable...

12) Two identical particles of charge 6 μC and mass 4 μg are initially at rest and held 4 cm apart. How fast will the particles move when they are allowed to repel and separate to very large (essentially infinite) distance? Answer: Last Answer Hint: The particles are identical, so you can assume that the scenario is symmetrical. Use energy conservation: What type of energy is stored in the system when the particles are near each other and at rest?...
