A 6.50 m, 0.732 kg wire is used to support two uniform 235 N posts of equal length (the figure (Figure 1)). Assume that the wire is essentially horizontal and that the speed of sound is 344 m/s. A strong wind is blowing, causing the wire to vibrate in its 5th overtone. Part A What is the frequency of the sound this wire produces? Express your answer with the appropriate units. ? f = Value Units Submit Request Answer Part B Figure 1 of 1 What is the wavelength of the sound this wire produces?

Consider the loaded shaft illustrated in Figure Q4 (i). The shaft is simply supported at A and D. The shoulder fillet radius is 0.3 cm at B and C. If the shaft is subjected to a force of F=800 N, determine the following:

II. A circular column is made of concrete [E. 4.2(10³)ksi] while being reinforced with six steel rods [Est = 29 (10³)ksi]. It is acted upon 4 in. - 30 kip by an axial force of 30 kip as shown in the figure to the right. Each rod has a diameter of 0.85 in. 3 ft Solve for the following: a) Force in each steel rod, Pst b) Force in the concrete, P. c) Stress in each steel rod, Ost = kip kip %3D ksi d) Stress in the concrete, oc = ksi

A force of F is applied on the system at A as shown in the figure in order to maintain the system in equilibrium.   ii) What are the magnitudes of the components of force F parallel and perpendicular to link AC?
