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.

Determine the location of the local minimum and/or maximum for the equation below which has roots at x=-1, x=-2, and x=-3.   

TRIGONOMETRIE Vraag 8 8.1 ‘n Houer ABCDEFGH het afmetings, lengte = 10m;  breedte = 5m en diepte = 6m soos getoon in die onderstaande skets.     Regsklik op die volgende skakel om die skets oop te maak in ‘n aparte “tab”.   8.1.1 Bepaal die lengte van die skuins AG. (4) 8.1.2 Bepaal dus, of anders, die grootte van die hoek θ = CÂG. (2) 8.2 Skuins-piramide, ABCDH, met ‘n vierkantige basis van 200 m, word hieronder getoon.  E is die middelpunt van AD en F is ‘n punt op AB, 50 m van BC. Die loodregte hoogte van die piramide is 7 m. Die toppunt van die piramide is 100 m van kant AB en 50 m van kant BC.     Regsklik op die volgende skakel om die skets oop te maak in ‘n aparte “tab”.   8.2.1 Bepaal die volume van die piramide met die formule: Volume = basisarea × hoogte.        (2) 8.2.2 Bepaal die lengte van AH.  (4) 8.2.3 As AH = 180,41 m, bepaal die grootte van die hoogtepunt AĤD. (2) 8.2.4 Vervolgens, of anders, bepaal die oppervlakte van driehoek AHD. (2)   TOTAAL [16]   GROOT TOTAAL [150]
