Rigid bar ABC shown in Figure P1.30 is supported by a pin at bracket A and by tie rod (1).

Rigid bar ABC shown in Figure P1.30 is supported by a pin at bracket A and by tie rod (1). Tie rod (1) has a diameter of 5 mm, and it is supported by double-shear pin connections at B and D. The pin at bracket A is a single-shear connection. All pins are 7 mm in diameter. Assume a = 600 mm, b = 300 mm, h = 450 mm, P = 900 N, and θ = 55°. Determine the following:

(a) the normal stress in rod (1)

---

 

(b) the shear stress in pin B

---

 

(c) the shear stress in pin A

The jet transport B is flying north with a velocity

The jet transport \(B\) is flying north with a velocity \(v_{\mathrm{B}}=600 \mathrm{~km} / \mathrm{h}\) when a smaller aircraft \(A\) passes underneath the transport headed in the \(60^{\circ}\) direction shown. To passengers in \(B\), however, \(A\) appears to be flying sideways and moving east. Determine the actual velocity of \(A\) and the velocity which \(A\) appears to have relative to \(B\).
