The __ (beam axle)provides a simple means of mounting the hub and wheel units. a . MacPherson strut b. SLA suspension C . Independent axle d. Solid axle

## Step 1<br />The problem is asking us to identify the type of axle that provides a simple means of mounting the hub and wheel units. The options provided are MacPherson strut, SLA suspension, Independent axle, and Solid axle.<br /><br />## Step 2<br />The MacPherson strut and SLA suspension are types of suspension systems, not axles. They are used to absorb shocks and maintain tire contact with the road, but they do not provide a simple means of mounting the hub and wheel units.<br /><br />## Step 3<br />The Independent axle is a type of axle where the wheels are independent of each other. This means that each wheel can move independently of the other, which is not the same as providing a simple means of mounting the hub and wheel units.<br /><br />## Step 4<br />The Solid axle, on the other hand, is a type of axle where the hub and wheel units are directly mounted on the axle shaft. This provides a simple means of mounting the hub and wheel units, as the axle shaft is the same as the hub and wheel unit.
