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".

4.Press j @ J 0 0 to set the angular unit to DEG, 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.

5.Press b 2 0, select the program ‘TENSION’ and press e.

6.Enter 30 [ 15 [ 20 for angle A and press e.

7.Enter 27 [ 45 [ 40 for angle B and press e.

8.Enter 40 for weight W and press e for S.

9.Press e for T.

Results

Tension in the strings S and T are 23.761 kg and 21.966 kg, respectively.

23.761 T=

21.966
