An object turns about a center with constant tangential speed of 5.425m/s. The object is attached to the center by means of a cord of length 2m, and of negligable weight. Determine the values of radius of rotation "R" and "h". (See attachment for full question)
At the instant that an object travels horizontally with a velocity of "v", passes at an elevation of "h" above a second object, the second object is released at an angle "x" to the horizontal with a velocity... (PLEASE SEE ATTACHMENT FOR COMPLETE PROBLEM AND DIAGRAM)
Calculus Based Dynamics (Given Instantaneous Radius of Curvature for Plane Curve is ... Find ... )
An object travels with a constant speed "v" in the x-y plane over a feature that is described by the equation {see attachment}. Given that the instantaneous radius of curvature for any plane curve is: {see attachment}, find the minimum value of "v" that makes the object "weightless" at the apex. Take "g" to equal 9.81 m/s[squ ...continues
Calculus Based Dynamics (Object Collision - Determine Points of Impact and Time of Impact)
Objects 1 and 2 are fired horizontally from the same elevation directly towards each other. Object 1 is fired with velocity {see attachment} while Object 2 is fired with velocity {see attachment}. Initial separation is 3m. Take "g" = 9.81 m/s[squared] - Determine the "x" value of the point of impact - Determine the time "ti" ...continues
Assignment Question 3 in Applied Mechanics
Fig. Q3 shows a rigid light beam which is hinged at O to a wall. The beam carries a point mass of m at the free end. The beam is connected at its mid-point to a spring (stiffness k) which is also connected to a support that moves with a vertical motion y = Y sinwt. A damper (coefficient c) connects the mid-point of the beam to a ...continues
Piston-gear mechanisms. See attached file for full problem description.
These problems are having to do with relative angular velocity adn acceleration. I get very close to the right answers, but i dont see where i am going wrong. can you please show me the soloutions so i can see where i went wrong on them.
Pair of blocks connected by a cord, one attached to a spring
This is one of two problems I've posted off a quiz I took last week and failed. Please give a detailed explanation when working out the problem. I'm trying to understand this so I don't fall behind in class. Thank you for all your help. Please see attached for a detailed description.
A pinned gear, D, drives an outer ring, C which is connected to three planet gears, B. If gear D rotates at a constant 3 rad/s, what is the angular velocity of gear B. The center or sun gear A is fixed (does not rotate). The raduis of the gears are: rA = 1 in, rB = 2 in, rC = 5 in, and rD = 1.5 in. (See attachment for all quest ...continues
