Evaluate the value of the following integral between the limits of 0 and [t], t is in radians.   Enter your answer to the second decimal place.  

Determine the tension T (Newtons) required to pull the 25 kg mass across the floor at a constant speed if the kinetic coefficient of friction between the floor and the block is 0.36 and the cable makes a 45 degree angle as shown.

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.
