1. Evaluate the nodal forces used to replace the linearly varying surface traction shown in Figure..


1. Evaluate the nodal forces used to substitute the linearly varying demeanor traction shown in Symbol P9–2. Hint: Use Eq. (9.1.34).

2. For an component of an axisymmetric substantiality rotating delay a constant disfigured speed o = 20 rpm as shown in Symbol P9–3, evaluate the body-force matrix. The coordinates of the component are shown in the symbol. Let the influence blindness pw be 0.283 lb/in3.
