Question
The industrial robot is held in the stationary position shown. Draw the shear and moment diagrams of the arm $A B C$ if it is pin connected at $A$ and connected to a hydraulic cylinder (two-force member) $B D$. Assume the arm and grip have a uniform weight of $1.5 \mathrm{lb} / \mathrm{in}$. and support the load of $40 \mathrm{lb}$ at $C$.
Step 1
The spring constant is given by the formula $K = \frac{W}{\Delta}$, where $W$ is the weight and $\Delta$ is the extension. Substituting the given values, we get $K = \frac{W}{9}$. Show more…

Two hydraulic cylinders control the position of the robotic arm $A B C .$ In the position shown, the cylinders are parallel and both are in tension. Knowing that $F_{A E}=600 \mathrm{N}$ and $F_{P G}=50 \mathrm{N},$ determine the forces $\mathrm{P}$ and $\mathrm{Q}$ applied at $C$ to arm $A B C .$

Two hydraulic cylinders control the position of the robotic arm $A B C .$ In the position shown, the cylinders are parallel and both are in tension. Knowing that $F_{A E}=600 \mathrm{N}$ and $F_{D G}=50 \mathrm{N}$ determine the forces $\mathbf{P}$ and $\mathbf{Q}$ applied at $C$ to arm $A B C$.
The robot arm is elevating and extending simultaneously. At a given instant, $\theta=30^{\circ}, \dot{\theta}=40 \mathrm{deg} / \mathrm{s}$ $\ddot{\theta}=120 \operatorname{deg} / \mathrm{s}^{2}, l=0.5 \mathrm{m}, \dot{l}=0.4 \mathrm{m} / \mathrm{s},$ and $\ddot{l}=-0.3$ $\mathrm{m} / \mathrm{s}^{2} .$ Compute the radial and transverse forces $F_{r}$ and $F_{\theta}$ that the arm must exert on the gripped part $P,$ which has a mass of 1.2 kg. Compare with the case of static equilibrium in the same position.
