Express each force acting on the pipe assembly in Cartesian vector form. The tower is held in place by three cables.

The pole is subjected to the force F, which has z components acting along the x, y, z axes as shown. The log is being towed by two tractors A and B. If two of the chains are subjected to known forces, as shown, determine the angle u of the third chain measured clockwise from the positive x axis, so that the magnitude of force F in this chain lb is a minimum.

Express this force as a Cartesian vector. Determine the magnitude and coordinate direction z angles of the resultant force acting at A. The spur gear is subjected to the two forces caused z by contact with other gears.

If the cord AB is 7. Solve the problem by finding the magnitude of rBC; then check the result by first finding qrAB, and rAC and then using the cosine law.

Determine the angle u between the two cables z attached to the post. All forces lie in the x—y plane. The three supporting cables exert the forces shown z on the sign.

Determine the magnitude and direction of the resultant force acting on the pipe assembly. Two cables solytion used to secure the overhang boom in z position and support the N load. This material is protected under all copyright laws as they currently exist. If the force in each cable tied to the bin is 70 lb, z determine the magnitude and coordinate direction angles fdition the resultant force.

What is the magnitude of this smallest resultant force? The truck is to be towed using two ropes. Determine the magnitude and coordinate direction z angles of the resultant force. Two forces act on the hook. Force F2 acts within the octant shown. If the force in each chain has a magnitude of lb, z determine the magnitude and coordinate direction angles of the resultant force.

Also, find the coordinate direction angles a and g. Three chains act on the bracket such that they create y a enginewring force having a magnitude of lb. Determine z the magnitude of the projected component of F1 along the line of action of F2.

Determine the length of side BC of the triangular z plate. Determine the coordinate direction angles of the z force F1 and indicate them on the figure. Both the x and y components of this force cause synovial fluid to be squeezed out of the bearing space. If the tension in the cable is N, determine the y N magnitude and direction of the resultant force acting on the pulley.

The enginsering is used on a jig. Click here to sign up. If two of the lb cables are subjected to known forces, as shown in the figure, determine the angle u of the third cable so that the magnitude of force F in this cable is a minimum. Force F acts in this direction. Determine the angle u between pipe segments z BA and BC.

The contact point between the femur and tibia y bones of the leg is at A.

Determine the y magnitude and direction u of F2 so that the resultant force is directed along the positive u axis and has a magnitude of 50 lb. The chandelier is supported by three chains which z are concurrent at point O.

Enter the email solutkon you signed up with and we’ll email you a reset link. Note that the y component represents the normal force on the load-bearing region of the bones.

First find the resultant of the two known forces. If the resultant msnual is required to act along the y positive u axis and have a magnitude of 5 kN, determine the required magnitude of FB and its direction u.

What is the component of force acting along member AB?

Two cables exert forces on the pipe. Determine the distance between the end points A z and B on the wire by first formulating a position vector from A to B and then determining its magnitude. If the resultant force acting on the bracket is y required to be a minimum, determine the magnitudes of F1 F1 u and the resultant force. If the force in each chain has a magnitude of 60 lb, express each force as a Cartesian vector and determine the magnitude and coordinate direction O angles of the resultant force.

The shaft S exerts three force components on the z die D. Determine the magnitude and coordinate z direction angles of F2 so that the resultant of the two forces acts along the positive x axis and has a magnitude of N. Two forces F1 and F2 act on the bolt. If the z force of each cable acting on the tower is shown, determine D the magnitude and coordinate direction angles a, b, g of the resultant force.
