For a short time the arm of the robot is extending at a constant rate such that dr/dt = 1.9 ft/s when r = 2.7 ft, z = (4t^2) ft, and ? = 0.5t rad, where t is in seconds. Determine the magnitude of the acceleration of Grip A when t = 3.4.

Step 1
4. r = 2.7 ft (given) z = 4t^2 ft = 4(3.4)^2 ft = 4(11.56) ft = 46.24 ft θ = 0.5t rad = 0.5(3.4) rad = 1.7 rad Show more…

At the instant shown, the robotic arm $A B C$ is being rotated simultaneously at the constant rate $\omega_{1}=0.15$ rad/s about the $y$ axis, and at the constant rate $\omega_{2}=0.25 \mathrm{rad} / \mathrm{s}$ about the $z$ axis. Knowing that the length of arm $A B C$ is $1 \mathrm{m}$, determine (a) the angular acceleration of the arm, $(b)$ the velocity of point $C,(c)$ the acceleration of point $C$.

Robots with telescoping arms are sometimes used to perform tasks (e.g., welding or placing screws) where access may be difficult for other robotic types. During a test run, a robot arm is programmed to extend according to the relationship $r=3+0.5 \cos (4 \theta)$ and the arm rotates according to the relationship $\theta=-\frac{\pi}{4} r^{2}+\pi t,$ where $r$ is in feet, $\theta$ is in radians, and $t$ is in seconds. Determine $(a)$ the velocity and acceleration of the robot tip $A$ at $t=3 \mathrm{~s}$ and $(b)$ use a computer program to plot the path of tip $A$ in $x$ and $y$ coordinates for $0 \leq t \leq 4 \mathrm{~s}$.
