Rigid member DB is pinned to rigid member ABD at joint B. Length a = 3 ft, length b = 4 ft, and length c = 2 ft.  Force F =300 lb is acting to the up at A. Determine the magnitude of the  force (lb) acting at joint B.

For which of the following fractional functions, can L’Hopital’s Rule be applied when determining the limit shown?

Find the electric field strength (V/m) for two parallel plates having a voltage potential difference of 5.0 Volts and which are separated [x] cm apart.   You may assume the plates are infinitely large.  

Truss ABCD is simply supported at joints A and C.  Force F = 200 N and acts downward at joint D.  Length AB = BC = 4m and length BD = 3m.  Determine the force (N) acting in member AD and its direction. (use + sign for tension and – sign for compression).

Find the allowable range for θ2 for the particle to remain in static equilibrium,  if F1, F2, and F3 are all arranged a shown in the figure.  

Evaluate the following derivative

The particle below is in static equilibrium.  If F1 = 100 lb and  F3 =50 lb,  determine the magnitude of F2 (lb).    

Rigid member DB is pinned to rigid member ABD at joint B.  Length a = 3 ft, length b = 4 ft, and length c = 3 ft.  Force F = 200 lb is acting to the right at A.  Determine the magnitude of the force (lb) acting at  joint B.  

Determine the second moment of area (cm4) about an y-axis that passes through the centroid for the section shown below.  The centroid is located 1.36 cm to the right of the left edge of the part.  All dimensions are cm.

A simple 5-Member Triangular Truss is loaded at joint D with a Horizontal force as shown in the figure.   Which of the following truss members are Zero-Force Members.  Recall that a Zero Force Member is a any single truss segment in which, given a specific load, is neither in tension, nor in compression.
