The man pushes The wheelbarrow at a steady speed with a force P= 150 N, which is parallel to the x-axis. The mass of the wheelbarrow with its contents is 60 kg with mass center at G. determine the normal forces NA and NB under each wheel A and B. Neglect friction. *

The solid homogeneous cylinder shown has a mass of 30 kg and is rotating at 1200 rpm clockwise about a fixed horizontal axis through O. The coefficient of kinetic friction between the brake and the cylinder is 0.20. If the tension in the spring when the brake is applied is 100 N, determine the time required for the cylinder to stop rotating. Neglect the thickness of the vertical members. (Draw FBD)

Problem 2: Rod AB has a mass of 10-kg and a uniform cross-sectional area. The piston has a mass of 15-kg. If the flywheel rotates at a constant angular velocity of 500 rev/min, determine the forces on A and B when 8 = 60°. Use a Vector Approach, show all your work. 150 mm, 750mm

With the 360-lb cylindrical part P in its grip, the robotic arm pivots about O through the range -45° ≤ 0 ≤ 45° with the angle at A locked at 120°. Determine and plot (as a function of 0) the moment at O due to the combined effects of the 360-lb part P, the 100-lb weight of member OA (mass center at G₁), and the 60-lb weight of member AB (mass center at G₂). The end grip is included as a part of member AB. The lengths L₁ and L₂ are 2.8 ft and 2.0 ft, respectively. What is the maximum absolute value of Mo and at what value of 0 does this maximum occur? The moment is positive if counterclockwise, negative if clockwise. After you have the plot, answer the questions. lb-ft lb-ft lb-ft 52 120⁰ G₂ G₁ T!

The motor lifts the 40-kg  crate with an acceleration of 6 m/s2 as shown in (Figure 1). Part A: Determine the x and y components of force reaction at the fixed support A using scalar notation. Express your answers in newtons to three significant figures separated by a comma.   Part B:  Determine the couple moment at the fixed support A. Express your answer in kilonewton meters to three significant figures. Enter positive value if the moment is counterclockwise and negative value if the moment is clockwise.

The 186-kg wheel has a radius of gyration about its center O of ko = 300 mm, and radius r = 0.4 m. When the wheel is subjected to the constant couple moment M = 92 N.m, it starts rolling from rest. Determine the average friction force that the ground applies to the wheel if it has been rolling without slipping. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper Sl unit. Take g = 9.81 m/s². M Your Answer: units Answer
