Determine the force F required to lift a 300 N load F, with each of the pulley systems shown in Figure below. Neglect friction and the weights of the pulleys.

NOTE - the reaction force is not shown on the free body diagram you just drew. Do you understand why? Perpendicular and Parallel Forces. A 500 +/- 1 g aluminum block sits in the middle of a balance. Strings with small mass hangers are attached as shown in the diagram. The mass hanger on the right has a total mass of 100 +/- 1 g. The hanger on the left has a mass of 50 +/- 0.5 g. Assume that the balance reads 400.1 +/- 0.1g. 50g Alum. Block Balance 100g As before, follow the procedure in the lab manual to obtain a free body diagram and ultimately the second law equations for the aluminum block. It will be easier if you separate the x and y forces and deal with each direction individually. When you have completed writing the second law equations above, answer the following questions: 2. What is the magnitude of the frictional force acting between the aluminum block and the balance? (You should be able to determine this from your free body diagrams.)

Please show all work and how you solved it. With proper units and full body diagram if needed, thanks

The 60 kg two-wheeled cart is described in the figure and parameter table below, with G indicating the location of the center of gravity. It is to be pulled so that it goes up the small step. Find the normal force on each wheel, and the magnitude and direction of the force applied at handle. HINT: remember that there are two wheels sharing the load @080 BY NO SA 2021 Cathy Zupke 4₁1 G L₁ L₂ parameter value 0.6 0.5 0.8 0.7 0.2 A L3 LA d L3 units m m m m m B L₂ F For the answers, take to the right and up to be the positive directions. The normal force at each wheel at A in the x direction is Ax= 150 XN The magnitude of the force at B is F Measured from the positive horizontal axis, the angle of F= 45 X° = 212 XN

(5) A B $15⁰ 6 in. 100 lb D C E What is the horizontal force on block E applied by the slider D if a = 4 in.? The slider is on wheels and can translate without friction. Draw free body diagrams of ABC and BD.

Need help. Please round answers to 3 sig figs

Write down equations for static equilibrium. Calculate the moment about C, and leave the answer in terms of the unknow force of magnitude |FB| After that Caclulate |FB|

A 68.4 kg man stands on his toes by exerting an upward force through the Achilles tendon, as shown in the figure. Part (a)  In units of newtons, what is the magnitude of the force through the Achilles tendon if he stands on one foot?  Part (b)  Calculate the force in units of newtons at the pivot of the simplified lever system shown. That force is representative of forces in the ankle joint.

1. Draw the Free Body Diagrams of pulleys A, B and C and F then using these FBD calculate the force F needed to hold the 1,200-lb force as shown. Assume all the pulleys and ropes to be weightless and ignore the friction between the ropes and pulleys. C B 1,200 lb
