Example
Calculate the tension in the strings S and T when the weight of the bar is
40 kg, angle A: 30° 15' 20" and angle B: 27° 45' 40".
Press j @ J 0 0 to set the angular unit to DEG,
4.
then @ J 1 0 3 to set display to fixed mode with the
decimal point of 3 .
• In this program input angles by degree/minute/second format. They will
be automatically converted to decimal degrees.
Press b 2 0, select the program 'TENSION' and press
5.
e.
Enter 30 [ 15 [ 20 for angle A and press e.
6.
Enter 27 [ 45 [ 40 for angle B and press e.
7.
Enter 40 for weight W and press e for S.
8.
Press e for T.
9.
Results
Tension in the strings S and T are 23.761 kg
and 21.966 kg, respectively.
