Determine force P on the cable if the spring is compressed 0.025 m when the mechanism is in the position shown. The spring has a stiffness of k = 6 kN/m. 去 150 mm 30- 200 mm 180 mm 700mm 160 mm

The bracket is held to the wall using three A-36 steel bolts at B, C, and D. Each bolt has a diameter of 0.5 in. and an unstretched length of 2 in. If a force of 800 lb is placed on the bracket as shown, determine how far, s, the top bracket at bolt D moves away from the wall. For the calculation, assume that the bolts carry no shear; rather, the vertical force of 800 lb is supported by the toe at A. Also, assume that the wall and bracket are rigid. A greatly exaggerated deformation of the bolts is shown.

Each member of the pin-connected mechanism has a mass of 8 kg as shown in Figure Q5. If the spring is unstretched at = 0°, determine the require stiffness k so that the mechanism is in equilibrium when 0 = 30°. Set M =0 D M 10 300 mm 300 mm Figure Q5 mi B 300 mm C
