The downward load of 2250 lb represents the weight of the shed. The horizontal vector of 1600 lb represents the resultant of the estimated load from the wind. The support at lower left corner is a hold-down strap with only vertical reaction. The support at the lower right corner is a pin-connection with both vertical and a How much downward force is required at point a to keep the shed from overturning? b. How much are the horizontal and the vertical reactions at the lower right corner?

Explanation / Answer

10 a)The angle the cable makes with the horizontal = tan-1(36/36) = 45o

Moment of T about point B = 86*sin45*20 = 1216.00 Nm (anticlockwise)

b)moment of W about B = 76*16 = 1216 Nm (clockwise)

c)Combined moment about B = 1216-1216. = 0
