Problems 10-16 Information: Jose' pushes a wheelbarrow consisting of a wheel (mass mw = 3 kg, radius r= 0.1 m) and a barrow body (mass mg = 30 kg). He accelerates from rest (state 1) to a velocity of 2 m/s (state 2), when he trips and lets the wheelchair roll down the hill (height h = 2 m, 30 deg angle) to the bottom (state 3), where it hits a crate (mass mc= 20 kg) into motion (state 4). The ground has a friction coefficient of 0.5. Between states 1 and 2, when Jose' is balancing the wheelbarrow, all the weight is on the wheel. After that, the support spike drags along the ground, holding half the total weight, while the other half is on the wheel. 13). Draw the FBD and write the equations of motion for the wheelbarrow descending the hill. What is its acceleration? (keep in mind there are 2 normal forces) 14. What is the speed at the bottom of the hill? 15. If the collision between the wheelbarrow and the crate has a coefficient of restitution e = 0.6, how fast does the crate move…

A mechanism to spray water onto vehicles at an automated car wash is shown. Classify the four-bar mechanism, based on its possible motion, when the lengths of the links are: a = 12 in b = 1.5 in C = 14 in d = 4 in Complete solution must be included in the file that will be uploaded at the end of assessment. Input the category type of the given four-bar mechanism in the space provided. For example, "DOUBLE CRANK" or "CRANK-ROCKER" etc. (refer to MODULE 1 for the table with the list of different categories.)

QUESTION 14 Which one of the below statements is true? For a grounded link rotating with constant angular speed, the magnitude of the velocity vector of a point increases as the point moves away from the pivot. Ob. Kutzbach formula (or criteriong is always reliable in predicting the actual degrees of freedom for any mechanism. C. Springs are considered as links for degree of freedom calculations. O d. Satistying the Grashof criterion means that none of the links in a mechanism makes full rotations.

Aim: To conduct a full kinematic analysis and calculate dynamic reaction forces in a linkage mechanism, calculate instantaneous torque, required to drive the mechanism and to present the results of the case study in a clear reporting format. Introduction: Figure 1 shows a pumpjack operating at an oil well. Its representation as a linkage is also shown in Figure 1. The pumpjack is driven by a motor attached to crank OA. A constant torque T is applied to the crank and the crank rotates at a constant angular velocity ???. A force P is applied vertically downwards at the end of the walking beam BD, which has its centre of mass at point G. To design the mechanism, a careful kinematic analysis of the mechanism needs to be conducted. To avoid mechanical failure and to provide adequate support to the mechanism, the engineer needs to analyse the reaction forces in the joints. Masses of links OA and AB are assumed to be smaller in comparison with the mass of BD and are ignored in the analysis.…
