The T-shaped structure is embedded in a concrete wall at A
and subjected to the force F₁ and the force-couple system
F2 1650 N and M = 1,800 N-m at the locations shown.
Neglect the weight of the structure in your calculations for
this problem.
=
a.) Compute the allowable range of magnitudes for F₁ in the
direction shown if the connection at A will fail when
subjected to a resultant moment with a magnitude of 920 N-
m or higher.
b.) Focusing on the forces and igonoring given M for now.
Using the value for F1, min that you calculated in (a), replace
the two forces F₁ and F2 with a single force that has
equivalent effect on the structure. Specify the equivalent
→>
force Feq in Cartesian components and indicate the
horizontal distance from point A to its line of action (note
this line of action may not intersect the structure).
c.) Now, model the entire force system (F1,min, F2, and M)
as a single force and couple acting at the junction of the
horizontal and vertical sections of the…
The heated rod from Problem 3 is subject to a volumetric heating
h(x) = h0
x
L in units of [Wm−3], as shown in the figure below. Under the
heat supply the temperature of the rod changes along x with the
temperature function T (x). The temperature T (x) is governed by the
d
following equations:
−
dx (q(x)) + h(x) = 0 PDE
q(x) =−k dT
dx Fourier’s law of heat conduction (4)
where q(x) is the heat flux through the rod and k is the (constant)
thermal conductivity. Both ends of the bar are in contact with a heat
reservoir at zero temperature.
Determine:
1. Appropriate BCs for this physical problem.
2. The temperature function T (x).
3. The heat flux function q(x).
Side Note: Please see that both ends of bar are in contact with a heat reservoir at zero temperature so the boundary condition at the right cannot be du/dx=0 because its not thermally insulated. Thank you
The elastic bar from Problem 1 spins with angular velocity ω about an axis, as shown in the figure below. The radial acceleration at a generic point x along the bar is a(x) = ω2x. Under this radial acceleration, the bar stretches along x with displacement function u(x). The displacement d u(x) is governed by the following equations: dx (σ(x)) + ρa(x) = 0 PDE σ(x) = E du dx Hooke’s law (2) where σ(x) is the axial stress in the rod, ρ is the mass density, and E is the (constant) Young’s modulus. The bar is pinned on the rotation axis at x = 0 and it is also pinned at x = L. Determine: 1. Appropriate BCs for this physical problem. 2. The displacement function u(x). 3. The stress function σ(x). SIDE QUESTION: I saw a tutor solve it before but I didn't understand why the tutor did not divide E under the second term (c1x) before finding u(x). The tutor only divided E under first term. please explain and thank you
