Consider four identical circular Euler columns under a
compressive axial load with a) one end fixed and the other pinned
(or hinged or simply-supported), b) both ends fixed, c) both ends
pinned (or hinged or simply-supported), d) one end fixed and the
other free. What are the buckling loads Pcr for each one and which
one is the strongest against buckling? Given are: the length L of
the column and bending rigidity EI, ?

A horizontal spring has one end fixed and one end attached to a
3 kg mass, which slides without friction. The spring has a
stiffness constant of 48 N/m. At time t = 0 the mass is at rest at
the origin when a driving force of F = 120 cos 6t (F is in newtons)
is applied.

the homogeneous solution (i.e., the solution to the motion when F =...

One end of a cord is fixed and a small 0.400-kg object is
attached to the other end, where it swings in a section of a
vertical circle of radius 1.00 m, as shown in the figure below.
When
θ = 18.0°,
the speed of the object is 7.50 m/s.
An object is swinging to the right and upward from the end of a
cord attached to a horizontal surface. The cord makes an angle
θ with the vertical. An...

One end of a cord is fixed and a small 0.550-kg object is
attached to the other end, where it swings in a section of a
vertical circle of radius 3.00 m, as shown in the figure below.
When θ = 17.0°, the speed of the object is 9.00 m/s. An object is
swinging to the right and upward from the end of a cord attached to
a horizontal surface. The cord makes an angle θ with the vertical.

Each of two identical uniform metal bars has a resistance
R.
The end of one bar is welded to the end of the other bar (Figure
1) . In terms of R, what is the resistance of this
combination?
What is the resistance if the bars are welded together along
their length? (Figure 2)
A 23.3-kg mass is attached to one end of a horizontal spring, with the other end of the spring fixed to a wall.
Part AA 23.3-kg mass is attached to one end of a horizontal spring, with the other end of the spring fixed to a wall. The mass is pulled away from the equilibrium position (x = 0) a distance of 17.5 cm and released. It then oscillates in simple harmonic motion with a frequency of 8.38 Hz. At what position, measured from the equilibrium position, is the mass 2.50 seconds after it is released?–5.23 cm16.6 cm–5.41 cm–8.84 cm–11.6 cm Part BA 23.3-kg...

There are three "methods" to compute and work problems to
calculate these figures. The first is simply by way of a
formula...(i.e. beginning finished goods + cost of goods
manufactured - ending finished goods = cost of goods sold). The
second was by visualizing the flow of goods throughout the various
T accounts for Raw Materials, Work in Process, and Finished Goods.
The third was to prepare journal entries in order to compute each
of these amounts, which is similar...
