1.The 30-N uniform rod has length of l=1m. If s=1.5m determine the distance h of placement at the end A along the smooth wall for equilibrium.
2.A 900-mm strip of steel is bent into a full circle by two couples applied as shown. Determine
(a) the maximum thickness t of the strip if the allowable stress of the steel is 420 MPa,
(b) the corresponding moment M of the couples. Use E 5 200 GPa. Radius Unknown, Thickness Unknown, 2 Moments at each end.
