Vehicle On 4 Jack Stands . . . Safe? - Car Talk Community A couple weeks ago I heard someone on the radio show mention supporting a vehicle with four jack stands, one at each “corner”, apparently by lifting one end with a jack, placing two stands, then doing the same at the other end I don’t remember if this was mentioned by Tom or Ray, or a caller, but I was left with the impression that it is an acceptable way to support a vehicle while
Calculations for Hydraulic Jacks lifting a load - Physics Forums The discussion focuses on the calculations involved in hydraulic jacks, specifically analyzing the relationship between forces and pressures in a system with a hand pump and a jack cylinder The hand pump has a piston area of 2 0 cm² and applies a force of 98 1 N, resulting in a pressure of 4 905 N cm² This pressure is transmitted to a jack piston with an area of 10 0 cm², allowing it to
Dangerous car jacks? - General Discussion - Car Talk Community The complete weight of whatever part of the car rests on the ratchet bar and its weight is subsequently held in place by that skinny pin In other words, in the past I had half of the cars weight rest on two skinny pins, one in each jack Thinking back, it sounds like attempted suicide to use these types of jacks on cars
Special car jack stand for sloped grades • Physics Forums The discussion revolves around the design and safety of a specialized jack stand intended for use on sloped surfaces Participants explore the feasibility, safety concerns, and potential designs for a jack stand that could operate effectively on uneven grades, considering both theoretical and practical implications One participant suggests designing a jack stand with a larger base and a
Ramps VS. car jack - Maintenance Repairs - Car Talk Community I’d like to change the oil in my car by myself I want to buy car ramps, but some people say a car jack is better I’d rather have the opinion of those with experience, so, which one is safer to use?
How Do You Calculate Tractive Force for Accelerating a Car? The discussion revolves around calculating the tractive force required for a car to accelerate from 0 to 160 km h in 4 2 seconds, considering a resistive force of 1000 N Participants explore the concepts of average acceleration, net force, and the relationship between forces acting on the car, including friction and air resistance The context includes both theoretical calculations and
Putting a car on blocks - Car Talk Community We will be leaving the country for 9 months, and plan to leave a car (actually a pick-up truck) in the garage Should the truck be put “on blocks,” and how do you do this?
How do I determine the force and torque requirements for a 12V DC car jack? A new type of jack is introduced, which combines features of hydraulic and screw jacks, prompting questions about converting pressure and force to torque Some participants express skepticism about the practicality of using a 12V DC motor for this application, suggesting alternative methods like air bags with electric fans
How to get the jack out of CRV? - Car Talk Community Hello, the jack in the trunk is a scissor jack To get the jack out of the trunk, the scissor jack needs to be closed compressed a little If you look in the trunk around the spare tire you should find a small tool bag It contains a lug wrench and it contains a tool to raise and lower the jack (it has a hooked end)
