- Q2/ A Body of weight of 40 Kg is pulled along a rough horizontal plane by pull of 20 N acting at an angle of 14 with the horizontal. Find the friction force and normal force (reaction)? 20 N 40 Kgarrow_forwardA force of P = 850 N is applied to the smaller cylinder of a hydraulic jack (Fig.2). The area a of the small piston is 15 cm2 and the area A of the larger piston is 150 cm2. What load W can be lifted on the larger piston if the pistons are at the same level, The mass density ρ of the liquid in the jack is 103 kg /m3.arrow_forwardPravinbhaiarrow_forward
- A pontoon boat floats on two cylindrical pontoons (assume the ends are flat). Each pontoon is 6m long. The mass of the boat, pontoons, and gear (without any passengers) is 1950 kg. If exactly half of the pontoon volume was submerged without any passengers on the boat, what is the maximum volume of water that can be displaced to support the weight of passengers? The density of freshwater is 1000 kg/m³ . End view of pontoons: Waterline Pontoon D/2 is submergedarrow_forwardA plane is fitted with pontoons for operation on lakes. As it taxies out for take-off, the plane itself weighs 10670 Newtons (2849lbs), it has 40 gallons of gasoline in its tanks, and the pilot and passenger together weigh 1513 Newtons (340 lbs). One gallon of gasoline weighs 25 Newtons (5.67lbs). What is buoyant force on the plane when it floats in a body of water? Take the mass density of water to be 1000 kg/m3 and the acceleration due to gravity as 9.8 m/s2 what volume of water do the pontoons displace?arrow_forwardA plane is fitted with pontoons for operation on lakes.

- Your answer is partially correct. A homogeneous, 4-ft-wide, 9.8 -ft-long rectangular gate weighing800lbis held in place by a horizontal flexible cable as shown in the figure below. Water acts against the gate, which is hinged at point A. Friction in the hinge is negligible, Determine the tension in the cable. AssumeL1=9.8ft,L2=7.2ft, andθ=57∘.

Thank you!arrow_forwardThe Weight of the Space Station The International Space Station operates at an altitude of 350 km. Plans for the final construction show that material of weight 4.22 x 106 N, measured at the Earth's surface, will have been lifted off the surface by various spacecraft during the construction process. What is the weight of the space station when in orbit? SOLUTION Conceptualize The mass of the space station is fixed; it is independent of its location. Based on the discussion in this section, we realize that the value of g will be reduced at the height of the space station's orbit. Therefore, the weight of the space station will be smaller than that at the surface of the Earth. Categorize We model the space station as a particle in a gravitational field Analyze From the particle in a field model, find the mass of the space station (in kg) from its weight at the surface of the Earth: m = g =| ]x kg Use the equation for the free-fall acceleration with h = 350 km to find the magnitude of the…arrow_forward

Ꮎ What is the weight carried by the builder at the rear? HINT: Consider the drywall to have no thickness. The builder at the rear gets tired and suggests that the drywall should be held by its narrow side. W 0 What is the weight he must now carry? HINT: From the previous problem, you know how much each builder carries. Therefore you know the total weight. Set the sum of the torques about the front lower corner to 0, so that you do not need to know the weight carried by the builder in front.arrow_forwardTwo builders carry a sheet of drywall up a ramp.
