Consider the following system in static equilibrium. Force vector Facts at a distance from the pin support at point O. Draw appropriate FBD as necessary. Assume frictionless pulleys If the reaction forces at O is zero and magnitude F is 169N, a. Find F and "a". (F need not necessarily be in the 4 quadrant as shown below) b.

1- Determine equilibrium the angle 9 for and investigate the stability of the mechanism in this position. The spring has a stiffness of k = 1.5 kN/m and is unstretched when 8 = 90°. The block A has a mass of 40 kg as shown in Fig.1. Neglect the mass of the links. quin 450 mm

The 18-lb box shown is attached to a spring that has a k=2 lb/in and an unstretched length of 14 inches. As shown the spring is stretched to a length of 20 inches. Solve for the unknown force P needed to keep the block in equilibrium. What is the normal force on the block? Assume the surface is smooth. (Note, "smooth" tells you friction is small enough to be neglected.) 20" TTTTTT P

The bobcat loader (Figure Q3) has a mass of 1200-kg, shows the center of mass is at G1. If there is a 200-kg pebble in the bucket, with center of mass at G2 determine the reactions of each pair of wheels A and B on the ground and the force in the hydraulic cylinder CD and at the pin E. There is a similar linkage on each side of the loader. L0.5 m E 0.1 m_ D 0.2 m G2 0.18 m G1 0.6 m 0.5 m В 0.45 m 1.2 m 0.15 m 0.2 m 0.05 m Figure Q3
