Review Three forces are applied to a wheel of radius 0.350 m, as shown in the figure (Figure 1). One force is perpendicular to the rim, one is tangent to it, and the other one makes a 40.0° angle with the radius. Assume that Fi = 11.7N, F2 = 14.2N, and F3 = 8.80N Part A What is the net torque on the wheel due to these three forces for an axis perpendicular to the wheel and passing through its...
Three forces of magnitudes F1=4.0N, F2=6.0N, and F3=8.0N are applied to a block of mass m=2.0kg, initially at rest, at angles shown on the diagram. (Figure 1) In this problem, you will determine the resultant (net) force by combining the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are positive).Part A: Calculate the magnitude of the resultant force F? r=F? 1+F? 2+F? 3 acting on the block.Express the magnitude of...

Learning Goal: Part A - Force with a known deflection To solve for forces in statically indeterminate bars with axial loads. When the number of reaction forces is greater than the number of equilibrium equations, the system is slatically indeterminate. Solving for the reactions requires some additional equations. These additional equations come from considering compatibility relationships (.e., continuity of displacements and relationships between displacements and loads). For an axially loaded member, the compatibility relationship for the deflections can be written...
Learning Goal: To solve for forces in statically indeterminate bars with axial loads. Consider a new structure, where the thickness of the bar is reduced to 32.5 mm from C to B (it is still square) (Figure 2) and <= 3.75 m. If the applied load is F - 370 kN , then what is the reaction at ? Let a positive reaction act to the right. The total length is still 6 m Express your answer with appropriate units...
