The high-wire for a circus act is attached to upright AC which in turn is kept vertical by tensioner rod BD as shown in the figure below. Upright AC is pinned to the floor-mounted clevis bracket at C using a 10 mm diameter steel pin as shown in View a-a and the accompanying section view. Note: it is not necessary to complete part a in order to complete parts b and c. a. The cable tension 'T' acting at point A is 9000 N. Show (using statical analysis) that the tensile load in tensioner rod BD is 1294O N and that the resultant of the reactions at point C is 7880 N. Tensioner rod BD is made from SAE 1080 OQT 1300 alloy steel and is 15 b. mm in diameter. Based on the stress in the middle of the rod, between points B and D, would it be suitable for a repeated tensile load of 12940 N? C. The shear load on the pin at C is 7880 N. Note the section view of joint C shown at right. Determine the minimum required pin diameter 'D' if it is made from SAE 4140 OQT 1300 alloy steel and must endure repeated loading.

a.
The cable tension 'T' acting at point A is 9000 N. Show (using statical
analysis) that the tensile load in tensioner rod BD is 12940 N and that the resultant of
the reactions at point C is 7880 N.
Tensioner rod BD is made from SAE 1080 OQT 1300 alloy steel and is 15
b.
mm in diameter. Based on the stress in the middle of the rod, between points B and
D, would it be suitable for a repeated tensile load of 12940 N?
C.
The shear load on the pin at C is 7880 N. Note the section view of joint C
shown at right. Determine the minimum required pin diameter 'D' if it is made from
SAE 4140 OQT 1300 alloy steel and must endure repeated loading.
The actual diameter of the pin used at joint C is 19 mm. If it is made from
d.
SAE 4140 OQT 1300 alloy steel what is the factor of safety of the pin based on
material yield strength in shear?
