- With no losses in the string-pulley system, calculate the force. Help please?Write down a relation expressing the mechanical advantage of a lever.Two forces FA =175 lb and FB =205 lb are acting on the bracket shown with axes x,y,v and w indicated. If the angle measurements on the figure are c=20o , d=9o , f=15o and g=7o, determine the x and ycomponent of FA and FB(lb).
- Expain the static equilibrium.Given: An object weighing 6500 kN in the figure What is wanted: Finding the mass m that will move the object. (Ground friction coefficient μs = 0.185, roller is frictionless.)A uniform beam weighs 200 N and holds a 450 N object one-quarter of the way from the right end of the beam. The beam is supported by ropes at both ends. Find the magnitude of the forces in the ropes. Express your answers in Newtons with the number rounded to the nearest whole number. Show your work, take a picture of it and upload it.
- Solve for the force P to obtain equilibrium. Angle of friction is 25° between block and the inclined plane.A force of 500 nt is measured with a possible error of 1 nt. Its component in adirection 60◦ away from its line of action is required, where the angle is subject to an error of 0.5◦. What is (approximately) the largest possible error in the component?For this answer i got 0.1593 m. but it was incorrect. not sure where I went wrong woth the spring force formula
