What is the minimum speed at which the MTVR can achieve a side slope of 40 percent?

The minimum speed at which the MTVR can achieve a side slope of 40 percent is 5 mph. This is because the vehicle's stability and traction are critically dependent on maintaining an adequate speed while traversing steep slopes. At 5 mph, the MTVR can optimize its performance and maintain control, ensuring that the center of gravity remains stable as it navigates the incline.

Maintaining a speed that's too low can result in a loss of momentum, which could lead to potential roll-over or traction issues, particularly on a side slope that presents a significant challenge. The design parameters and engineering of the MTVR are configured to enhance its maneuverability and safety, especially when traversing challenging terrains. Thus, understanding the relationship between speed, slope angle, and vehicle stability is essential for operating the MTVR effectively in various conditions.

The other options present higher speeds which may not be necessary for navigating the specified slope, and could lead to unnecessary wear on the vehicle or higher risks in terms of the operational dynamics involved when dealing with such an incline.
