Question 2 (35 points) 800mm The 20kg homogeneous cylinder of 800-mm diameter rests against the surfaces shown. The coefficient of static friction is 0.5 for AB and 0.6 for AC. The coefficient of kinetic friction is 0.4 for AB and 0.5 for AC 30- (1) 5 points: Draw the free body diagram of the cylinder (ii) 15 points: Calculate the magnitude of the clockwise couple M required to initiate the rotation. (iii) 15 points: Suppose that the contact at the...
Chapter 6, Problem 6/011 GO Tutorial The 28-kg homogeneous cylinder of 350-mm diameter rests against the vertical and inclined surfaces as shown. If the coefficient of static friction between the cylinder and the surfaces is 0.28, calculate the applied clockwise couple M which would cause the cylinder to slip Answer: M- N-m the tolerance is +/-1 in the 3rd significant digit
Prob. A 20-b uniform disk is placed in contact with an inclined surface and a constant 7.5 lb-ft couple M is applied as shown. The weight of the link AB is negligible. Knowing that the coefficient of kinetic friction at D is 0.4, determine (a) the angular acceleration of the disk, (b) the force in the link AB. a rough horizontal surface and end B supported by a smooth vertical surface. Knowing that the deceleration of the truck is 12...
i need to find the slope and whatever else they are asking Calculating the Coefficient of Static Friction (Pinewood on painted steal) From Empirical Data Background: **An object at rest remains at rest unless a force is applied to it." This paraphrases a portion of Newton's First law of motion. In the case of this lab a minimum amount of force must be applied to overcome the attraction between two surfaces. The amount of force needed to start the motion...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
summatize the following info and break them into differeng key points. write them in yojr own words apartus 6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
