2.  1.73 N  solution
3.  1764 Nm  solution (cos should be sin, otherwise OK)
4.  0.70 m  solution
5.  919 N  solution
6.  6.52 kg  solution

7.  1519 N  solution
10.  3.00 m  solution
11.  3.26 m  solution
13.  T1=235 N, T2=177 N  solution
16.  48.2 N; T must be very big because it has hardly any component in the vertical direction  solution

15.  14,700 N up, 2940 N down  solution
25.  89.5 cm from feet  solution
26.  T = 542.2 N, Fx = 409.2 N right, Fy = 5.72 N down  solution (has a problem -- what did I leave out?)
27.  T = 247.2 N, Fx = 247.2 N, Fy = 196 N  solution
42.  the tower is stable since the CM is not over extended; 2.55 m further  solution
