The truss is made from seven members, each having a mass of 6 kg/m. Locate the position (
,
) of the center of mass. Neglect the mass of the gusset plates at the joints.
= 2.36 m, = 1.286 m = 2.33 m, = 1.333 m = 2.43 m, = 1.308 m = 2.79 m, = 1.757 m7.
Locate the center of gravity of the volume generated by revolving the shaded area about the z axis. The material is homogeneous.
= 2.80 ft = 2.50 ft = 2.67 ft = 3.00 ft8.
Locate the center of gravity of the homogeneous "bell-shaped" volume formed by revolving the shaded area about the y axis.
= 3.33 ft = 2.80 ft = 3.20 ft = 3.00 ft9.
Locate the centroid of the exparabolic segment of area.
= -4a/5, = -b/4 = -3a/4, = -3b/10 = -2a/3, = -b/3 = -5a/7, = -3b/8Quick links
