The curvilinear motion of a particle is defined by v, = 50 – 16t and y =100 – 4t’, where v, is in meters per second, y is in meters, and t is in seconds.It is also known that x = 0 when t – 0. Plot the path of the particle and determine its velocity and acceleration when the position y = 0 is reached.

To plot the path of the particle, we need to find the expression for x in terms of t. We know that the velocity v_x is given by: vx=dxdt=50−16t𝑣𝑥=𝑑𝑥𝑑𝑡=50−16𝑡 Integrating with respect to t, we get: ∫dx=∫(50−16t)dt∫𝑑𝑥=∫(50−16𝑡)𝑑𝑡 x=50t−8t2+C𝑥=50𝑡−8𝑡2+𝐶 Given that x = 0...

A motor drives two loads. One has rotational motion. It is coupled to the motor through a reduction gear with a = 0.1 and efficiency of 90%. The load has a moment of inertia of 10.kg- m ^ 2 and a torque of 10 N-m. Other load has translational motion and consists of 1000 kg weight to be lifted up at an uniform speed of 1.5 m/s. Coupling between this load and the motor has an efficiency of 85%. Motor has an inertia of 0.2kg – m ^ 2 and runs at a constant speed of 1420 rpm. Determine equivalent inertia referred to the shaft and power developed by the motor.

• If the motor is rated at 19kW, is the motor sufficient to drive the two loads? • The translational motion load now has to lift a weight of 1200 kg at the same speed of 1.5m/s. Is the motor still capable to drive both loads at the same motor speed of 1420 rpm? Answer...
