The disk is1.2 m above the reference line shown. Determine(a) the radius of the disk, (b) angular acceleration,and (c) horizontal and vertical components ofacceleration of the disk.
The propeller on Don Karnage's airplane can be modeled as three identical thin rods of uniform density extending radially from the rotational axis of the propeller. To take off, the propeller must accelerate from rest to 633 rpm in 4 s. If the length and mass of each rod are 0.872 m and 3.11 kg, what must be the magnitude of torque in N*m) necessary to accelerate the propeller? Explain how you solved the problem involving something undergoing angular acceleration Be sure to state what your known and unknown quantities are, what concepts were applied, and what equations were used!
A Lazy Susan (M=0.5 kg) in the shape of a disk is free to rotate about its center withoutfriction. It is initially motionless when a Texas-sized cockroach (m=10 g) starts runningCCW along the rim. The angular speed of the Lazy Susan is then 1 rad/sec. With whatspeed is the cockroach running (in the rest frame of the table, not the Lazy Susan)? (What more data should be given according to you? If the question seems incomplete to you...)
The disk with a mass of 0.4 kg and a radius of 2 cm (I = 1 / 2mr ^ 2) slows down as it rolls on a flat surface. While the motion of the disc is the result of the moment of inertia, the friction coefficient is 0.1. Calculate the torque responsible for the deceleration of the disc
This is a dynamics problem. Answer: kO = 2.17 m
A uniform solid disk of mass 2.0 kg and radius 0.30 m is initially at rest. It is then rotated by a constant torque about an axis through its center of mass until it reached an angular speed of 3.0 rad/s. What is the work done by the constant torque? The moment of inertia through the center of mass is (2/5)MR^2.
In the system in the figure, the total mass of two plates of the same thickness, made of the same material and connected to each other is 70 kg. What is the angular acceleration of the system? (A1=1 m, B1=0.6 m. A2=1.2 m, B2=0.4 m, M=50 Nm)
The frame of a gyroscope in fig. is supported at O so that it can turn freely in alldirections. The wheel is a uniform disc of 10 cm diameter weighing 2 kg with its centre20 cm from O. The frame alone weighs 1 kg with centre of gravity G1, 12 cm from O.If the wheel spins as shown at 10,000 r.p.m. with its axle in the horizontal plane, findthe time required for the axle to make one revolution about O. Mention the direction ofthis rotation. Find also the vertical and horizontal forces by the support on the frame.
Blocks A and B shown in the figure have masses of 5 kg and 10 kg respectively.If the pulley is treated as a 3 kg solid disk with a 15 cm radius, determine the acceleration of the block A. Disregard the rope mass and any slip on the pulley.Consider that the moment of inertia of the pulley is given by Ip = (1/2)mr² in which m is the mass of the pulley and r is of radius the pulley.
Mason is is trying to keep a door open using a door stopper. That door is solid, and it has a mass of 18.3kg. The door closer is connected 26.2cm away from the hinge, and pulls with a force of 123N. The door stopper provides a static friction force of 13.2N, and a kinetic friction force off 11.8N. Find the angular acceleration (as a vector) of the door.
Hello, can you help me answer this question with complete solution and illustration. *A Land Cruiser having a mass of 1500 kg goes through an intersection and i stravelling from north to south when it is hit by a Mitsubishi Pajero of mass 220 kg travelling from east to west. The two cars slid as one due to impact and stops 5.39 m west and 6.43 m south measured from impact point. It is known that the coefficient of kinetic friction between the cars and the road is 0.75. How fast each of the car is travelling before collision?
Referring to Prob. 18.143, (a) prove that the Poinsot ellipsoid is tangent to the invariable plane, (b) show that the motion of the rigid body must be such that the Poinsot ellipsoid appears to roll on the invariable plane. [Hint: In part a, show that the normal to the Poinsot ellipsoid at the tip of w is parallel to HO. It is recalled that the direction of the normal to a surface of equation F (x,y,z), ) = constant at a point is the same as that of grad F at point P.J
